WEBVTT 00:00:00.000 --> 00:00:02.859 Welcome to the Deep Dive. It's really great to 00:00:02.859 --> 00:00:04.900 have you with us today. Our mission today is 00:00:04.900 --> 00:00:07.419 pretty specific. Yeah, and it's a fascinating 00:00:07.419 --> 00:00:10.259 one, honestly. We are looking at a really comprehensive 00:00:10.259 --> 00:00:13.539 breakdown of trench warfare. And our goal here 00:00:13.539 --> 00:00:15.919 is to get underneath the actual mechanics of 00:00:15.919 --> 00:00:19.289 it. We want to understand the why. Right do moot 00:00:19.289 --> 00:00:22.769 cause exactly, you know how a highly specific? 00:00:23.629 --> 00:00:26.449 Lethal mismatch between technology and mobility 00:00:26.449 --> 00:00:29.070 essentially force millions of men to just live 00:00:29.070 --> 00:00:31.489 underground and beyond just the history We're 00:00:31.489 --> 00:00:33.829 gonna look at how the brutal logic of those exact 00:00:33.829 --> 00:00:36.170 tactics is actively shaping the battlefields 00:00:36.170 --> 00:00:39.049 of the 21st century That mismatch is really the 00:00:39.049 --> 00:00:41.329 crucial element. It is when you study the actual 00:00:41.329 --> 00:00:43.490 mechanics and the evolution of trench warfare 00:00:44.649 --> 00:00:47.390 It quickly stops being just this historical set 00:00:47.390 --> 00:00:49.990 piece from World War I. It becomes this ongoing, 00:00:50.030 --> 00:00:52.469 highly adaptable response to an environment where 00:00:52.469 --> 00:00:55.469 weapons have just completely outpaced a human 00:00:55.469 --> 00:00:57.590 being's physical ability to move across open 00:00:57.590 --> 00:01:00.049 ground. Okay, let's unpack this. Because tracing 00:01:00.049 --> 00:01:01.909 this back, it is very clear that digging into 00:01:01.909 --> 00:01:04.310 the earth is definitely not a 20th century invention. 00:01:04.599 --> 00:01:07.579 Oh no, not at all. Armies have utilized trenches 00:01:07.579 --> 00:01:10.000 for basically as long as they've had shovels. 00:01:10.040 --> 00:01:12.200 Right, like the Roman legions. They operated 00:01:12.200 --> 00:01:14.079 on these strict protocols where they would dig 00:01:14.079 --> 00:01:17.379 in trenched fortified camps every single night 00:01:17.379 --> 00:01:19.549 while they were on the march. Yes. And you see 00:01:19.549 --> 00:01:22.609 major strategic applications early on, too. During 00:01:22.609 --> 00:01:25.969 the Battle of the Trench in 627 A .D., Salman 00:01:25.969 --> 00:01:28.930 the Persian successfully proposed digging a massive 00:01:28.930 --> 00:01:31.609 defensive trench to protect Medina from a much 00:01:31.609 --> 00:01:34.450 larger cavalry force. Just completely neutralizing 00:01:34.450 --> 00:01:37.209 the enemy's mobility advantage. Exactly. And 00:01:37.209 --> 00:01:39.629 as firearms entered the picture, the engineering 00:01:39.629 --> 00:01:42.370 just adapted to match. Look at the New Zealand 00:01:42.370 --> 00:01:45.269 wars in the mid 19th century. The Maori developed 00:01:45.269 --> 00:01:47.590 these fortified areas known as Pah. And those 00:01:47.590 --> 00:01:49.989 feature highly sophisticated trench and bunker 00:01:49.989 --> 00:01:52.290 systems, right? Very sophisticated. They were 00:01:52.290 --> 00:01:55.230 even weaving damp flax into the defenses to absorb 00:01:55.230 --> 00:01:57.569 incoming musket balls. That's brilliant. And 00:01:57.569 --> 00:01:59.750 then just a few decades later during the American 00:01:59.750 --> 00:02:02.390 Civil War, you have the sieges at Vicksburg and 00:02:02.390 --> 00:02:05.430 Petersburg devolving into these massive sprawling 00:02:05.430 --> 00:02:07.989 trench networks. You even see the Union Army 00:02:07.989 --> 00:02:10.969 deploying early rapid -fire Gatling guns in those 00:02:10.969 --> 00:02:14.379 exact trenches. So the tactical concept of fortifying 00:02:14.379 --> 00:02:17.000 the earth was very well established. But something 00:02:17.000 --> 00:02:19.960 fundamentally broke those existing rules of engagement 00:02:19.960 --> 00:02:23.639 in 1914. It did. At the outbreak of World War 00:02:23.639 --> 00:02:26.780 I, the military establishments of the major European 00:02:26.780 --> 00:02:30.280 powers simply hadn't absorbed the grim reality 00:02:30.280 --> 00:02:32.639 of the new technology they had stockpiled. They 00:02:32.639 --> 00:02:34.939 were dealing with a massive sudden revolution 00:02:34.939 --> 00:02:38.000 in firepower. A revolution that completely rendered 00:02:38.000 --> 00:02:40.699 their existing tactical doctrines obsolete. We're 00:02:40.699 --> 00:02:42.780 talking about a leap in technology that made 00:02:42.780 --> 00:02:45.680 traditional infantry charges mathematically impossible. 00:02:45.939 --> 00:02:48.460 Precisely. Take the rapid firing artillery of 00:02:48.460 --> 00:02:51.599 the era, most notably the French 75. This wasn't 00:02:51.599 --> 00:02:53.979 just a bigger cannon. It featured a revolutionary 00:02:53.979 --> 00:02:56.460 hydro -pneumatic recoil mechanism. So when it 00:02:56.460 --> 00:02:59.060 fired, the barrel slid back to absorb the force. 00:02:59.159 --> 00:03:01.400 But the carriage and the wheels stayed perfectly 00:03:01.400 --> 00:03:03.719 still. Meaning, the artillery crew didn't have 00:03:03.719 --> 00:03:06.039 to spend time repositioning and re -aiming the 00:03:06.039 --> 00:03:09.080 gun after every single shot. Exactly. A well 00:03:09.080 --> 00:03:12.659 -trained crew could fire 15 highly accurate, 00:03:12.919 --> 00:03:15.460 high -explosive fragmentation rounds every single 00:03:15.460 --> 00:03:17.759 minute. Wow. And then you combine that with the 00:03:17.759 --> 00:03:19.919 widespread adoption of the Maxim machine gun. 00:03:20.240 --> 00:03:22.879 which was water -cooled and belt -fed. Allowing 00:03:22.879 --> 00:03:25.360 it to fire continuously for hours without overheating. 00:03:25.580 --> 00:03:27.900 Right. And the lethality of the battlefield just 00:03:27.900 --> 00:03:30.460 multiplied exponentially. If we connect this 00:03:30.460 --> 00:03:32.979 to the bigger picture, the core problem was that 00:03:32.979 --> 00:03:35.960 firepower evolved, but mobility did not. Because 00:03:35.960 --> 00:03:38.479 European militaries had built their entire strategies 00:03:38.479 --> 00:03:41.740 around the decisive sweeping flank maneuver since 00:03:41.740 --> 00:03:45.000 Napoleon. Yes, which relied on troops marching 00:03:45.000 --> 00:03:47.560 or riding horses across open terrain. But you 00:03:47.560 --> 00:03:49.620 cannot march a column of men across a field when 00:03:49.620 --> 00:03:52.500 a single water -cooled machine gun can fire 600 00:03:52.500 --> 00:03:54.939 rounds a minute from a mile away. Because that 00:03:54.939 --> 00:03:57.919 lethal math made moving above ground physically 00:03:57.919 --> 00:04:01.090 impossible, the entire war just shifted downward. 00:04:01.310 --> 00:04:03.889 It wasn't a strategic choice. No it was an urgent 00:04:03.889 --> 00:04:06.509 desperate biological imperative to put earth 00:04:06.509 --> 00:04:09.449 between human flesh and flying steel and that's 00:04:09.449 --> 00:04:11.949 what triggered the infamous race to the sea in 00:04:11.949 --> 00:04:15.599 late 1914. Right. When those initial frontal 00:04:15.599 --> 00:04:19.300 assaults failed so catastrophically, both sides 00:04:19.300 --> 00:04:21.819 tried to outflank each other. They kept moving 00:04:21.819 --> 00:04:24.139 further and further north, digging in as they 00:04:24.139 --> 00:04:26.160 went. Always trying to reach the open flank. 00:04:26.300 --> 00:04:28.500 But they just kept running into more men with 00:04:28.500 --> 00:04:31.319 shovels and machine guns until they literally 00:04:31.319 --> 00:04:34.579 ran out of land. Which resulted in a continuous 00:04:34.579 --> 00:04:37.720 unbroken network of trenches stretching roughly 00:04:37.720 --> 00:04:40.879 400 miles from the Swiss Alps all the way to 00:04:40.879 --> 00:04:43.579 the North Sea. The old maneuvers were geographically 00:04:43.579 --> 00:04:46.000 impossible. And that required an entirely new 00:04:46.000 --> 00:04:48.779 type of architecture. It's a really common misconception 00:04:48.779 --> 00:04:51.579 that trenches were just long straight ditches 00:04:51.579 --> 00:04:54.279 cut into a field, but they were always dug in 00:04:54.279 --> 00:04:57.680 a jagged zigzag or stepped pattern. That architectural 00:04:57.680 --> 00:05:00.319 shift represents a profound psychological and 00:05:00.319 --> 00:05:02.680 tactical change. A straight trench is actually 00:05:02.680 --> 00:05:04.860 a death trap. Because if enemy troops breach 00:05:04.860 --> 00:05:07.500 a straight line, they can utilize inflating fire. 00:05:07.879 --> 00:05:10.019 Exactly. Shooting straight down the entire length 00:05:10.019 --> 00:05:12.360 of the trench, essentially wiping out the defenders. 00:05:12.600 --> 00:05:14.939 So they broke the trench up into distinct, separated 00:05:14.939 --> 00:05:17.319 segments called fire bays, connected by these 00:05:17.319 --> 00:05:19.740 sharp turns. It ensured that an enemy entering 00:05:19.740 --> 00:05:22.639 the trench only had access to a few yards of 00:05:22.639 --> 00:05:25.360 space before hitting a blind corner. But more 00:05:25.360 --> 00:05:28.120 importantly, the zigzag design was about surviving 00:05:28.120 --> 00:05:31.319 the sky. The artillery. Right. If a high explosive 00:05:31.319 --> 00:05:34.250 shell landed inside trench, the angles of the 00:05:34.250 --> 00:05:36.370 fire bay contained the blast -over pressure and 00:05:36.370 --> 00:05:39.310 the shrapnel entirely within that small section. 00:05:39.529 --> 00:05:42.949 Quarantining the destruction. And the environment 00:05:42.949 --> 00:05:45.250 dictated so much of how these networks were engineered 00:05:45.250 --> 00:05:48.389 too. Because geography doesn't care about military 00:05:48.389 --> 00:05:50.769 strategy. Take the Flanders region of Belgium. 00:05:51.009 --> 00:05:53.810 Where the water table is incredibly high. Sometimes 00:05:53.810 --> 00:05:56.129 just a meter below the surface. If you tried 00:05:56.129 --> 00:05:59.069 to dig a subterranean trench, you just hit groundwater 00:05:59.069 --> 00:06:01.750 and the hole flooded instantly. So they had to 00:06:01.750 --> 00:06:04.069 build upward. In Flanders, many of the trenches 00:06:04.069 --> 00:06:05.629 weren't dug into the earth at all. They were 00:06:05.629 --> 00:06:08.750 actually massive above -ground breastworks constructed 00:06:08.750 --> 00:06:11.990 from thousands of clay -filled sandbags and timber. 00:06:12.230 --> 00:06:14.870 And then at the complete opposite geographical 00:06:14.870 --> 00:06:17.709 extreme, you have the Italian front fighting 00:06:17.709 --> 00:06:20.290 the Austro -Hungarians in the Alps. Which wasn't 00:06:20.290 --> 00:06:22.990 mud. This was vertical rock and glacial ice. 00:06:23.209 --> 00:06:25.850 We are talking about artillery positions and 00:06:25.850 --> 00:06:29.069 trench networks carved into solid limestone and 00:06:29.069 --> 00:06:31.870 actual glaciers 12 ,000 feet above sea level. 00:06:32.009 --> 00:06:35.170 The logistics of the Alpine Front are just staggering. 00:06:35.370 --> 00:06:38.089 They had to construct massive aerial ropeways 00:06:38.089 --> 00:06:41.069 just to transport timber, ammunition, and food 00:06:41.069 --> 00:06:43.410 up the mountainsides. Just to keep the men alive. 00:06:43.610 --> 00:06:46.230 And in the Marmalade Glacier, Austro -Hungarian 00:06:46.230 --> 00:06:49.529 engineers actually drilled miles of tunnels deep 00:06:49.529 --> 00:06:52.589 inside the moving ice itself to create a complex 00:06:52.589 --> 00:06:55.850 known as the Ice City, protecting the soldiers 00:06:55.850 --> 00:06:58.430 from both Italian artillery and the freezing 00:06:58.430 --> 00:07:01.089 temperatures. Here's where it gets really interesting. 00:07:01.360 --> 00:07:03.160 Because when you think about soldiers living 00:07:03.160 --> 00:07:05.199 in these extreme environments, whether it's the 00:07:05.199 --> 00:07:08.160 mud of France or the ice of the Alps, the cultural 00:07:08.160 --> 00:07:10.319 myth is that a soldier went to the frontline 00:07:10.319 --> 00:07:13.199 trench and basically lived there for years. But 00:07:13.199 --> 00:07:15.620 the reality of the military roster was highly 00:07:15.620 --> 00:07:18.439 systematized. A typical British soldier actually 00:07:18.439 --> 00:07:21.079 only spent about 15 percent of their year actively 00:07:21.079 --> 00:07:23.040 stationed on the frontline. Because the high 00:07:23.040 --> 00:07:26.220 command recognized very quickly that continuous 00:07:26.220 --> 00:07:29.379 exposure to frontline conditions would physically 00:07:29.379 --> 00:07:32.350 and psychologically break a human being in a 00:07:32.350 --> 00:07:35.410 matter of weeks. So they instituted a strict 00:07:35.410 --> 00:07:38.509 rotation system. It's almost like extreme high 00:07:38.509 --> 00:07:40.970 -stress shift work. That's a really good analogy. 00:07:41.370 --> 00:07:43.550 A battalion might spend four to six days in the 00:07:43.550 --> 00:07:46.139 frontline fire trench. Then they would rotate 00:07:46.139 --> 00:07:48.860 back to a support trench for another few days, 00:07:48.879 --> 00:07:51.300 serving as the immediate backup. And from there, 00:07:51.300 --> 00:07:53.300 they'd move further back to the reserve lines. 00:07:53.600 --> 00:07:56.160 And finally, they would rotate entirely out of 00:07:56.160 --> 00:07:59.720 the trench system to a rear area for rest, refitting, 00:07:59.899 --> 00:08:02.279 and training. So the breakdown was roughly 15 00:08:02.279 --> 00:08:05.720 % on the front, 10 % in support, 30 % in reserve, 00:08:05.939 --> 00:08:08.860 and 20 % at rest, with the remainder spent on 00:08:08.860 --> 00:08:11.420 travel or hospital leave. It has a completely 00:08:11.420 --> 00:08:13.379 different rhythm to how you picture their daily 00:08:13.379 --> 00:08:16.170 existence. However, we do have to note a severe 00:08:16.170 --> 00:08:19.149 tragic exception to this rotation system. Right. 00:08:19.329 --> 00:08:21.769 The Portuguese Expeditionary Corps. Yes. They 00:08:21.769 --> 00:08:23.850 deployed to the Western Front and found themselves 00:08:23.850 --> 00:08:27.089 in an impossible logistical situation. Because 00:08:27.089 --> 00:08:30.050 Portugal lacked the shipping capacity and the 00:08:30.050 --> 00:08:32.789 political backing at home to send a steady stream 00:08:32.789 --> 00:08:36.070 of reinforcements. Precisely. The war of attrition 00:08:36.070 --> 00:08:38.409 was grinding down their numbers, and there were 00:08:38.409 --> 00:08:41.029 simply no fresh troops to replace the exhausted 00:08:41.029 --> 00:08:44.049 ones. Because of this severe manpower crisis, 00:08:44.509 --> 00:08:47.210 the rotation system completely collapsed for 00:08:47.210 --> 00:08:49.629 them, leaving some Portuguese units holding the 00:08:49.629 --> 00:08:51.730 front line trenches for up to six consecutive 00:08:51.730 --> 00:08:54.710 months without any relief. It was a test of human 00:08:54.710 --> 00:08:56.629 endurance that pushes the bound boundaries of 00:08:56.629 --> 00:08:59.269 comprehension. Which naturally brings us to the 00:08:59.269 --> 00:09:02.230 actual lethal conditions inside the mud they 00:09:02.230 --> 00:09:05.269 were living in. We know artillery was the primary 00:09:05.269 --> 00:09:08.730 threat. It was responsible for roughly 75 % of 00:09:08.730 --> 00:09:11.029 all combat casualties during the war. But the 00:09:11.029 --> 00:09:13.830 microscopic threats were arguably just as devastating 00:09:13.830 --> 00:09:16.370 to a battalion's operational capacity. Because 00:09:16.370 --> 00:09:19.190 the specific geography of the battlefield weaponized 00:09:19.190 --> 00:09:21.460 the microscopic environment. The western front 00:09:21.460 --> 00:09:23.860 cut right through the heavily agricultural regions 00:09:23.860 --> 00:09:26.419 of France and Belgium. Meaning the soil had been 00:09:26.419 --> 00:09:29.000 intensely fertilized with livestock manure for 00:09:29.000 --> 00:09:31.559 centuries. Teeming with Clostridium bacteria. 00:09:31.769 --> 00:09:35.730 Exactly. And if a soldier caught a piece of shrapnel 00:09:35.730 --> 00:09:38.830 and that highly infectious dirt was pushed deep 00:09:38.830 --> 00:09:42.049 into the wound, the bacteria thrived in the oxygen 00:09:42.049 --> 00:09:44.429 -depleted tissue. Which frequently led to gas 00:09:44.429 --> 00:09:46.809 gangrene. The infection would spread incredibly 00:09:46.809 --> 00:09:49.389 fast, literally producing gas bubbles beneath 00:09:49.389 --> 00:09:51.750 the skin and causing the tissue to go necrotic. 00:09:51.950 --> 00:09:55.190 In 1914, roughly 12 % of wounded British soldiers 00:09:55.190 --> 00:09:57.509 developed gas gangrene. And it's estimated to 00:09:57.509 --> 00:10:00.889 have directly killed over 100 ,000 German soldiers 00:10:00.889 --> 00:10:03.220 alive. Then you had the vectors living on the 00:10:03.220 --> 00:10:06.139 soldiers themselves. Trench fever was a massive 00:10:06.139 --> 00:10:09.980 issue. It caused severe debilitating bone pain, 00:10:10.399 --> 00:10:13.419 especially in the shins, and a relapsing fever 00:10:13.419 --> 00:10:15.700 that could leave a man bedridden and lethargic 00:10:15.700 --> 00:10:18.220 for months. And it was transmitted by the feces 00:10:18.220 --> 00:10:20.600 of the body lice that infested the troops' clothing 00:10:20.600 --> 00:10:22.700 in the cramped dugouts. When a soldier scratched 00:10:22.700 --> 00:10:25.200 a louse bite, they rubbed the infected feces 00:10:25.200 --> 00:10:27.379 into the micro abrasions in their skin. Over 00:10:27.379 --> 00:10:30.019 a million Allied soldiers contracted trench fever 00:10:30.019 --> 00:10:32.159 over the course of the war. And we can't ignore 00:10:32.159 --> 00:10:34.460 trench foot. The trenches were frequently flooded 00:10:34.460 --> 00:10:36.980 with near freezing water. Standing in that water 00:10:36.980 --> 00:10:39.519 for days on end caused the blood vessels in the 00:10:39.519 --> 00:10:42.200 feet to constrict. The tissue would go numb, 00:10:42.639 --> 00:10:45.899 swell, and eventually die. It caused 75 ,000 00:10:45.899 --> 00:10:48.720 British and 2 ,000 American casualties before 00:10:48.720 --> 00:10:50.840 the military bureaucracy realized they could 00:10:50.840 --> 00:10:54.639 mitigate it simply by enforcing systematic daily 00:10:54.639 --> 00:10:57.399 foot inspections and applying whale oil. The 00:10:57.399 --> 00:11:00.019 physical ailments were devastating, but the psychological 00:11:00.019 --> 00:11:02.639 toll of this environment was entirely unprecedented 00:11:02.639 --> 00:11:05.480 in military history. This was the birth of shell 00:11:05.480 --> 00:11:08.700 shock. And the claustrophobia of the trench heavily 00:11:08.700 --> 00:11:11.379 amplified that terror. If an artillery barrage 00:11:11.379 --> 00:11:13.500 started, you couldn't retreat. You couldn't charge. 00:11:13.820 --> 00:11:15.539 You just had to sit at the bottom of a hole, 00:11:15.720 --> 00:11:18.080 sometimes for days, waiting to see if a shell 00:11:18.080 --> 00:11:20.440 was going to land directly on you. Industrial 00:11:20.440 --> 00:11:23.379 warfare broke human psychology in a way the military 00:11:23.379 --> 00:11:26.309 establishment was entirely unprepared for. Men 00:11:26.309 --> 00:11:28.929 suffered severe nervous breakdowns. Developing 00:11:28.929 --> 00:11:31.549 uncontrollable tremors, blindness, or becoming 00:11:31.549 --> 00:11:34.129 completely catatonic. Just powering in the mud, 00:11:34.509 --> 00:11:37.070 unable to process the sheer volume of concussive 00:11:37.070 --> 00:11:39.549 force and sensory overload. But early in the 00:11:39.549 --> 00:11:42.289 war, many commanders genuinely didn't understand 00:11:42.289 --> 00:11:45.549 shell shock as a neurological or psychiatric 00:11:45.549 --> 00:11:48.429 medical condition. Wait, so if this was clearly 00:11:48.429 --> 00:11:51.289 a widespread involuntary physical and mental 00:11:51.289 --> 00:11:54.710 breakdown, Why did the military hierarchy treat 00:11:54.710 --> 00:11:57.289 it as a disciplinary issue? Were they just choosing 00:11:57.289 --> 00:11:59.789 to ignore the reality? You have to view it through 00:11:59.789 --> 00:12:03.450 the lens of 19th century military doctrine, which 00:12:03.450 --> 00:12:06.889 still highly prized stoicism, discipline, and 00:12:06.889 --> 00:12:10.029 sheer willpower. They viewed it as malingering 00:12:10.029 --> 00:12:12.870 or a failure of moral character. They saw it 00:12:12.870 --> 00:12:15.750 as a contagion of cowardice. Exactly, a contagion 00:12:15.750 --> 00:12:17.470 that could spread through the ranks and break 00:12:17.470 --> 00:12:20.029 a battalion's discipline. Which led to horrifying 00:12:20.029 --> 00:12:22.720 consequences. Tragically, yes. Because it was 00:12:22.720 --> 00:12:24.919 classified as cowardice or desertion in the face 00:12:24.919 --> 00:12:27.720 of the enemy, severely traumatized men were subjected 00:12:27.720 --> 00:12:30.679 to court marshals. The British Army officially 00:12:30.679 --> 00:12:34.679 executed 306 of its own soldiers by firing squad 00:12:34.679 --> 00:12:37.039 during the war before the medical reality of 00:12:37.039 --> 00:12:39.519 the condition was fully accepted. It's an unbelievably 00:12:39.519 --> 00:12:42.679 brutal environment. And that brutality heavily 00:12:42.679 --> 00:12:45.340 influenced the close quarters combat inside the 00:12:45.340 --> 00:12:47.700 trenches themselves. Because if you think about 00:12:47.700 --> 00:12:50.600 it, A standard -issue infantry rifle with a two 00:12:50.600 --> 00:12:53.200 -foot bayonet attached to the end of it is practically 00:12:53.200 --> 00:12:55.559 useless when you're fighting in a ditch that's 00:12:55.559 --> 00:12:58.200 only four feet wide. It was a massive liability. 00:12:58.379 --> 00:13:00.899 If you stabbed an enemy soldier, the long bayonet 00:13:00.899 --> 00:13:03.860 often wedged deeply into their rib cage. In the 00:13:03.860 --> 00:13:05.799 precious seconds it took to wrench the blade 00:13:05.799 --> 00:13:08.700 free, you were entirely defenseless against the 00:13:08.700 --> 00:13:11.080 next man coming around the fire bay corner. So 00:13:11.080 --> 00:13:14.259 the soldiers tossed the textbook out and improvised. 00:13:14.419 --> 00:13:17.340 They went medieval. Crafting short. weighted 00:13:17.340 --> 00:13:20.700 wooden clubs, metal maces, brass knuckles, and 00:13:20.700 --> 00:13:23.259 heavy trench knives. The most favored melee weapon 00:13:23.259 --> 00:13:25.620 was often just a standard entrenching spade, 00:13:25.879 --> 00:13:27.879 with the edges filed down until they were razor 00:13:27.879 --> 00:13:30.480 sharp. And eventually, the military -industrial 00:13:30.480 --> 00:13:33.620 complex recognized the need to institutionalize 00:13:33.620 --> 00:13:36.360 these close -quarters tactics. This claustrophobic 00:13:36.360 --> 00:13:39.120 environment directly birthed entirely new classes 00:13:39.120 --> 00:13:41.840 of specialized weaponry. The German Army introduced 00:13:41.840 --> 00:13:44.860 the Flammenwerfer. the first modern flamethrowers, 00:13:45.279 --> 00:13:47.360 which were terrifyingly effective at clearing 00:13:47.360 --> 00:13:50.100 deeply fortified dugouts. And the Americans brought 00:13:50.100 --> 00:13:52.779 over the pump -action shotgun. They took hunting 00:13:52.779 --> 00:13:55.360 shotguns, shortened the barrels, added heat shields, 00:13:55.639 --> 00:13:58.960 and loaded them with buckshot. They were so devastatingly 00:13:58.960 --> 00:14:01.419 efficient at clearing a narrow trench that it 00:14:01.419 --> 00:14:04.480 actually sparked an international incident. That's 00:14:04.480 --> 00:14:06.879 a fascinating nuance regarding the rules of war. 00:14:07.080 --> 00:14:10.120 It really is. The German government filed a formal 00:14:10.120 --> 00:14:12.600 diplomatic protest, arguing that the shotgun 00:14:12.600 --> 00:14:15.019 was an illegal weapon that caused unnecessary 00:14:15.019 --> 00:14:18.120 suffering, violating the Hague conventions. They 00:14:18.120 --> 00:14:20.860 even threatened to immediately execute any American 00:14:20.860 --> 00:14:23.759 prisoner captured carrying one. The U .S. essentially 00:14:23.759 --> 00:14:26.500 ignored the protest, but it highlights how the 00:14:26.500 --> 00:14:29.200 trench environment forced adaptations that blurred 00:14:29.200 --> 00:14:31.740 the accepted lines of warfare. You also see the 00:14:31.740 --> 00:14:34.019 invention of the submachine gun. specifically 00:14:34.019 --> 00:14:37.440 for this purpose. The German MP18 was designed 00:14:37.440 --> 00:14:39.759 around the concept of a soldier sweeping through 00:14:39.759 --> 00:14:42.399 a trench, firing fully automatic pistol rounds 00:14:42.399 --> 00:14:45.179 at targets only a few feet away. But with all 00:14:45.179 --> 00:14:47.940 of this incredible firepower and these massive, 00:14:48.120 --> 00:14:51.240 continuous defensive networks, how did anyone 00:14:51.240 --> 00:14:53.879 ever break the deadlock? Yeah, if the generals 00:14:53.879 --> 00:14:57.259 realized by 1915 that charging into machine guns 00:14:57.259 --> 00:14:59.539 was suicidal, why did they keep doing it for 00:14:59.539 --> 00:15:02.200 three more years? Was it just sheer incompetence? 00:15:02.399 --> 00:15:05.139 It's easy to look back and label it incompetence, 00:15:05.159 --> 00:15:07.500 but the reality is they were trapped by a lack 00:15:07.500 --> 00:15:10.340 of tactical alternatives and communication technology. 00:15:11.000 --> 00:15:13.299 Once the infantry went over the top, the general 00:15:13.299 --> 00:15:16.919 sitting in Chateau's miles behind the lines had 00:15:16.919 --> 00:15:19.460 zero way to communicate with them because radios 00:15:19.460 --> 00:15:21.440 were too massive and fragile. They relied on 00:15:21.440 --> 00:15:24.080 runners or carrier pigeons. So they kept attempting 00:15:24.080 --> 00:15:26.220 massive frontal assaults because they were desperately 00:15:26.220 --> 00:15:29.019 trying to find a mathematical formula. The exact 00:15:29.019 --> 00:15:32.200 right ratio of days long artillery bomb. bombardments 00:15:32.200 --> 00:15:34.120 to infantry numbers that would snap the enemy 00:15:34.120 --> 00:15:36.220 line. But the artillery just churned the ground 00:15:36.220 --> 00:15:38.659 into an impassable swamp, making it even harder 00:15:38.659 --> 00:15:41.500 for the infantry to advance. Breaking the deadlock 00:15:41.500 --> 00:15:44.399 required entirely new tactical paradigms, not 00:15:44.399 --> 00:15:46.179 just more men. Right. On the tactical front, 00:15:46.299 --> 00:15:48.740 the Germans developed infiltration tactics, sometimes 00:15:48.740 --> 00:15:52.240 called udia tactics. Instead of a massive miles 00:15:52.240 --> 00:15:55.919 wide wave of thousands of men, they trained elite, 00:15:56.360 --> 00:15:59.279 heavily armed units called stormtroopers. Who 00:15:59.279 --> 00:16:01.360 completely ignored the strong points. Exactly. 00:16:01.519 --> 00:16:03.960 They moved quickly, probing the line for weak 00:16:03.960 --> 00:16:06.320 spots. When they found one, they punched through 00:16:06.320 --> 00:16:08.279 and immediately pushed deep into the enemy's 00:16:08.279 --> 00:16:10.519 rear to attack artillery positions and command 00:16:10.519 --> 00:16:13.299 posts. Leaving the front line strong points isolated 00:16:13.299 --> 00:16:16.779 and confused to be mocked up by regular infantry 00:16:16.779 --> 00:16:19.500 later. And on the technological side, you have 00:16:19.500 --> 00:16:22.059 the British and French inventing the tank. Those 00:16:22.059 --> 00:16:25.360 early tanks had that distinct, massive, rhomboid 00:16:25.360 --> 00:16:28.559 shape for a very specific reason. They were engineered 00:16:28.559 --> 00:16:31.120 explicitly to physically crush acres of barbed 00:16:31.120 --> 00:16:33.379 wire and have tracks long enough to drive right 00:16:33.379 --> 00:16:36.139 over a wide trench without falling in. And finally, 00:16:36.299 --> 00:16:38.639 there was the strategy of going underneath the 00:16:38.639 --> 00:16:41.159 stalemate entirely. Mining became an intensely 00:16:41.159 --> 00:16:43.799 specialized aspect of trench warfare. Armies 00:16:43.799 --> 00:16:46.299 recruited civilian coal miners and formed dedicated 00:16:46.299 --> 00:16:48.720 tunneling companies. They would dig shafts deep 00:16:48.720 --> 00:16:51.080 into the clay beneath no man's land, sometimes 00:16:51.049 --> 00:16:53.070 working in complete silence using a technique 00:16:53.070 --> 00:16:55.830 called clay kicking to avoid detection by enemy 00:16:55.830 --> 00:16:58.070 listening posts. They would dig right under the 00:16:58.070 --> 00:17:00.970 enemy's front line trench and pack the subterranean 00:17:00.970 --> 00:17:03.789 chamber with staggering amounts of a monal explosives. 00:17:03.990 --> 00:17:06.690 There is an incredible quote from British General 00:17:06.690 --> 00:17:09.730 Herbert Plumer speaking to his staff the evening 00:17:09.730 --> 00:17:12.890 before they detonated a massive series of mines 00:17:12.890 --> 00:17:16.150 at the Battle of Messines in 1917. He said, gentlemen. 00:17:16.599 --> 00:17:18.960 We may not make history tomorrow, but we shall 00:17:18.960 --> 00:17:21.220 certainly change the geography." And he meant 00:17:21.220 --> 00:17:24.519 it literally. The next morning, they detonated 00:17:24.519 --> 00:17:28.380 19 massive mines simultaneously. It instantly 00:17:28.380 --> 00:17:30.779 vaporized the German front line and threw millions 00:17:30.779 --> 00:17:33.180 of tons of Earth thousands of feet into the air. 00:17:33.380 --> 00:17:35.460 The shockwave was supposedly felt in London. 00:17:36.000 --> 00:17:38.140 It was a literal reshaping of the Earth's crust 00:17:38.140 --> 00:17:41.380 to bypass a tactical stalemate. So what does 00:17:41.380 --> 00:17:43.900 this all mean? When we study the Battle of Messiaen 00:17:43.900 --> 00:17:46.440 or the Somme, it's very tempting to look at trench 00:17:46.440 --> 00:17:49.559 warfare as a horrific anomaly of early 20th century 00:17:49.559 --> 00:17:52.559 history. A painful growing pain of the Industrial 00:17:52.559 --> 00:17:55.000 Revolution that we eventually evolved past once 00:17:55.000 --> 00:17:57.059 we perfected tanks and airplanes in World War 00:17:57.059 --> 00:17:59.640 II. This raises an important question. Did trench 00:17:59.640 --> 00:18:02.160 warfare actually disappear or did it just go 00:18:02.160 --> 00:18:04.839 dormant waiting for the right conditions? Because 00:18:04.839 --> 00:18:08.039 while World War II was defined by rapid, mechanized 00:18:08.039 --> 00:18:11.000 maneuver warfare, the trenches never truly vanished. 00:18:11.440 --> 00:18:14.519 No. Whenever armies reach parity or whenever 00:18:14.519 --> 00:18:16.920 mobility is restricted by terrain or technology, 00:18:17.339 --> 00:18:19.480 the shovel becomes the most important tool on 00:18:19.480 --> 00:18:22.740 the battlefield again. We saw massive, static 00:18:22.740 --> 00:18:25.460 trench networks utilized extensively during the 00:18:25.460 --> 00:18:28.299 Iran -Iraq War in the 1980s. And you see it heavily 00:18:28.299 --> 00:18:32.359 in the 1991 Gulf War. Saddam Hussein constructed 00:18:32.359 --> 00:18:34.700 the Saddam Line along the Saudi -Kuwait border. 00:18:35.180 --> 00:18:37.700 It was a massive, complex fortification straight 00:18:37.700 --> 00:18:40.160 out of World War I, complete with barbed wire 00:18:40.160 --> 00:18:42.380 minefields and deep trenches filled with oil, 00:18:42.579 --> 00:18:44.660 ready to be set on fire. But the United States 00:18:44.660 --> 00:18:47.279 military bypassed it not by engaging in a prolonged 00:18:47.279 --> 00:18:49.940 war of attrition, but by utilizing overwhelming 00:18:49.940 --> 00:18:53.059 armored mobility. They used M1 Abrams tanks equipped 00:18:53.059 --> 00:18:55.400 with massive anti -mine plows to drive straight 00:18:55.400 --> 00:18:57.640 down the trench lines. Effectively burying the 00:18:57.640 --> 00:19:00.079 defenses and tragically many Iraqi defenders 00:19:00.079 --> 00:19:02.720 alive under tons of desert sand in a matter of 00:19:02.720 --> 00:19:05.180 hours. But the most chilling modern evolution 00:19:05.180 --> 00:19:08.380 we are seeing right now is in the Russo -Ukrainian 00:19:08.380 --> 00:19:12.099 War. We are witnessing a massive, undeniable 00:19:12.099 --> 00:19:15.660 return to static, trench -based warfare in Eastern 00:19:15.660 --> 00:19:17.599 Europe. And it's not because the armies lack 00:19:17.599 --> 00:19:20.140 tanks or modern equipment. It is entirely driven 00:19:20.140 --> 00:19:23.240 by highly lethal 21st century technology forcing 00:19:23.240 --> 00:19:26.079 men back underground. It's the same core mismatch 00:19:26.079 --> 00:19:29.700 we saw in 1914, just operating on a new technological 00:19:29.700 --> 00:19:31.980 spectrum. Today, the battlefield is dominated 00:19:31.980 --> 00:19:35.339 by an incredibly tight ISR loop. intelligence 00:19:35.339 --> 00:19:38.099 surveillance and reconnaissance driven primarily 00:19:38.099 --> 00:19:41.839 by drones yes cheap ubiquitous commercial drones 00:19:41.839 --> 00:19:44.200 alongside sophisticated military surveillance 00:19:44.200 --> 00:19:46.500 mean the battlefield is entirely transparent 00:19:46.500 --> 00:19:49.140 you cannot mass a battalion of tanks or a company 00:19:49.140 --> 00:19:51.779 of infantry for a sweeping flank maneuver the 00:19:51.779 --> 00:19:54.019 moment you step out of a tree line a drone spots 00:19:54.019 --> 00:19:57.119 you within seconds highly precise gps guided 00:19:57.119 --> 00:20:00.119 artillery or an explosive suicide drone is actively 00:20:00.119 --> 00:20:02.680 targeting your position it is surreal to observe 00:20:02.680 --> 00:20:04.940 we are seeing the exact exact same muddy trench 00:20:04.940 --> 00:20:07.579 networks, the exact same zigzag firebases, the 00:20:07.579 --> 00:20:10.559 same shattered stumps of charred trees. But instead 00:20:10.559 --> 00:20:12.819 of hiding from a Maxima machine gun firing across 00:20:12.819 --> 00:20:15.740 a field, the soldiers are hiding from a $500 00:20:15.740 --> 00:20:18.539 quadcopter hovering a thousand feet above their 00:20:18.539 --> 00:20:21.660 heads. The tactical geometry has changed. The 00:20:21.660 --> 00:20:23.940 trench isn't just a horizontal barrier to stop 00:20:23.940 --> 00:20:27.460 a bullet. It is a vertical shield to hide from 00:20:27.460 --> 00:20:29.940 the sky. And because the drones make the front 00:20:29.940 --> 00:20:33.019 line so deeply porous, even the logistical supply 00:20:33.019 --> 00:20:35.960 lines miles behind the trenches are incredibly 00:20:35.960 --> 00:20:38.740 vulnerable. Transporting a single crate of rations 00:20:38.740 --> 00:20:41.740 to a front line dugout is a highly lethal operation. 00:20:42.180 --> 00:20:44.420 And that really brings us back to why unpacking 00:20:44.420 --> 00:20:47.329 this matters for you, the listener. Understanding 00:20:47.329 --> 00:20:49.730 the mechanics of trench warfare isn't just a 00:20:49.730 --> 00:20:52.130 grim exercise in memorizing military history. 00:20:52.349 --> 00:20:54.549 It's about deeply understanding the raw limits 00:20:54.549 --> 00:20:57.049 of human endurance when we find ourselves trapped 00:20:57.049 --> 00:20:59.769 between rapidly advancing technology and the 00:20:59.769 --> 00:21:02.009 hard, rigid realities of the physical world. 00:21:02.269 --> 00:21:04.849 It forces you to think about how our own innovations, 00:21:05.390 --> 00:21:08.029 our brilliant new machines, our drones, our tactical 00:21:08.029 --> 00:21:10.970 systems, often have the power to trap us completely 00:21:10.970 --> 00:21:13.009 before they ever figure out a way to liberate 00:21:13.009 --> 00:21:15.990 us. It's a sobering reality of human conflict. 00:21:15.950 --> 00:21:20.190 And to leave you with one final physical reminder 00:21:20.190 --> 00:21:23.410 of that history, remember those massive explosive 00:21:23.410 --> 00:21:25.569 mines the British tunneling companies planted 00:21:25.569 --> 00:21:27.809 deep under the German lines at the Battle of 00:21:27.809 --> 00:21:30.609 Messines in 1917? The ones that changed the geography. 00:21:30.970 --> 00:21:33.019 Right. They planted a series of them, but due 00:21:33.019 --> 00:21:35.339 to severed detonation wires and the chaos of 00:21:35.339 --> 00:21:38.420 the assault, they didn't all go off. The precise 00:21:38.420 --> 00:21:41.960 locations of two of those heavily packed undetonated 00:21:41.960 --> 00:21:44.859 mines were mislaid after the war. They were just 00:21:44.859 --> 00:21:47.259 lost to the bureaucratic shuffle of history. 00:21:47.799 --> 00:21:51.319 Wow. Decades later in 1955, a massive lightning 00:21:51.319 --> 00:21:53.700 strike from a thunderstorm traveled down into 00:21:53.700 --> 00:21:55.720 the ground and actually triggered one of them, 00:21:55.940 --> 00:21:58.740 blowing a massive crater into the Belgian countryside 00:21:58.740 --> 00:22:01.539 completely unprompted. And the final one. It 00:22:01.539 --> 00:22:03.900 is still there. It remains hidden under the earth 00:22:03.900 --> 00:22:07.059 somewhere beneath a farm in Europe today. A silent 00:22:07.059 --> 00:22:09.359 sleeping monster packed with thousands of pounds 00:22:09.359 --> 00:22:12.079 of high explosives from the Great War still waiting 00:22:12.079 --> 00:22:14.500 beneath the ground. That is definitely something 00:22:14.500 --> 00:22:17.039 to think about. Thanks for joining us on this 00:22:17.039 --> 00:22:18.359 deep dive. We'll catch you on the next one.
