The Battle of Amiens: The Hundred Days Offensive That Ended WWI

0:00Lucas: So we've talked a lot about 1918 — the Kaiserschlacht, the German spring offensives, how they pushed deep into France but never broke through. What we haven't really covered is what happened next, once the German offensives ran out of steam. That's where the Allied counter-offensive began — what became known as the Hundred Days Offensive. Luna: Right, the Hundred Days — I've heard that term, but isn't it a bit misleading? Did it really last a hundred days? Lucas: Pretty much — from August 8 to November 11, 1918, exactly 95 days. And it started with one battle that Ludendorff himself called 'the black day of the German Army' — the Battle of Amiens. Lucas: On August 8, 1918, near the town of Amiens in northern France, the British Fourth Army under Henry Rawlinson launched a massive surprise attack. But this wasn't like the earlier offensives — they had learned from years of mistakes. The key was combined arms: infantry, tanks, artillery, and aircraft all coordinated together. Luna: What made this attack different from, say, the Nivelle Offensive or the Kaiserschlacht? Lucas: For one thing, there was no preliminary bombardment. The Germans knew a big barrage meant an attack was coming. Instead, the Allies used a creeping barrage — a moving curtain of shells that advanced just ahead of the infantry — and they fired it without warning. The tanks — over 500 of them, mostly Mark V and Whippet tanks — moved with the infantry, not ahead of them. And the aircraft, including Sopwith Camels, strafed German trenches and machine-gun nests. Lucas: The results were stunning. On the first day alone, the Allies advanced up to 12 kilometers in some places — a huge gain by WWI standards. The Canadians under Arthur Currie and the Australians under John Monash punched through the German lines near the village of Villers-Bretonneux. The German Second Army, under General Georg von der Marwitz, was caught completely off guard. Luna: Ludendorff called it a black day. What did he mean by that? Lucas: He wrote in his memoirs that August 8 was the worst day of the war for the German Army. It wasn't just the territorial losses — it was the morale collapse. Whole German units surrendered without a fight. Troops shouted 'You're prolonging the war!' at reinforcements being sent forward. Ludendorff realized that the war could no longer be won militarily. Lucas: One story that captures the shock: near the village of Caix, a single Whippet tank named 'Musical Box' — commanded by Lieutenant C.B. Arnold — drove behind German lines for nine hours, cutting telephone wires and machine-gunning troops. It was eventually knocked out, but the crew survived. That kind of chaos was happening everywhere. Luna: And this was the start of a hundred days of Allied advances that ended the war? Lucas: Exactly. After Amiens, the Allies kept up the pressure. The British attacked at the Somme, the Americans at Saint-Mihiel, the French along the Aisne. The German Army was being pushed back everywhere, and by October, the High Command knew they had to ask for an armistice. But Amiens was the turning point — it proved that the German Army could be defeated decisively. Lucas: One thing I want to highlight — the role of the Canadian Corps. They were maybe the best Allied offensive force in 1918. At Amiens, they advanced 13 kilometers on the first day, captured over 5,000 prisoners, and did it with relatively low casualties for that kind of attack. Their commander, Arthur Currie, insisted on meticulous planning — every soldier knew their objective. Luna: So it wasn't just brute force — it was precision. Lucas: Exactly. Currie was a master of 'set-piece' battles. He used aerial reconnaissance photos to map German trenches, and he insisted on rehearsing the attack behind the lines with marked-out terrain. The Canadians also used machine-gun barrages and smoke screens to cover their advances. And the Australian Corps under Monash used similar methods — they were both incredibly effective. Lucas: On the German side, the situation was dire. Their best troops — the Stosstruppen — had been exhausted during the spring offensives. Replacements were poorly trained, and morale was sinking. The Allied use of tanks and aircraft was something the Germans couldn't match. By August 8, the German Army was a shadow of what it had been in March. Luna: And what about the French and American forces at Amiens? Lucas: The French First Army under General Debeney attacked on the right flank of the British. They also made gains, though not as deep. The American 33rd Division, under General George Bell Jr., fought alongside the Australians and captured the town of Chipilly. The Moroccan Division — part of the French colonial troops — also fought bravely. So it was a truly Allied effort. Lucas: But the battle wasn't a total walkover. After the first two days, the German resistance stiffened. They brought up reserves and fortified new positions. The Allied advance slowed, and by August 12, the offensive was halted. They had gained about 24 kilometers at the deepest point, but they'd also taken over 20,000 casualties. Luna: So the Hundred Days didn't end the war in a single stroke — it was a relentless grind that wore Germany down. Lucas: Exactly. Amiens broke the psychological barrier, but it was followed by battles like the Second Battle of the Somme, the Hindenburg Line breakthrough, and the Meuse-Argonne Offensive. Each one pushed the Germans back a bit more. By late September, Ludendorff suffered a nervous collapse, and by early October, Germany was asking for peace. Lucas: For anyone coming with us through these conversations — about World War I, about the decisions and sacrifices that shaped the 20th century — you might have noticed we don't run ads. That's deliberate. Fexingo is listener-supported, and it's what keeps these episodes independent and focused on history. A couple of dollars a month is genuinely what keeps these going. If you've gotten something out of them, you can find us at buy me a coffee dot com slash fexingo. Luna: It really does make a difference. And it's how we keep digging into topics like this one, that don't always get the attention they deserve. Lucas: So the Battle of Amiens — it's not as famous as the Somme or Verdun, but in many ways it was more decisive. It proved that the Allies had finally learned how to break the trench deadlock. And it set the stage for the armistice just 95 days later. Luna: What happened to the town of Amiens itself after the war? Lucas: Amiens was heavily damaged. The cathedral — one of the largest Gothic cathedrals in France — was hit by shells, but it survived. The city was rebuilt after the war. Today, there's a memorial to the battle, and the Australian and Canadian contributions are remembered there. It's a quiet place now, but in August 1918, it was the pivot point of the war.
