They called it a suicide walk—800 yards of open wheat field swept by German machine guns—and the Marines went anyway.

The Guns of Belleau Wood: When U.S. Marines Entered the Great War's Hell

The Bloody Baptism That Forged America's Modern Military Legend

In June 1918, U.S. Marines walked into German machine guns at Belleau Wood and refused to stop—changing the Great War.

The wheat field stretched golden before them, deceptively peaceful in the June morning sun. Sergeant Dan Daly, a wiry veteran who had already earned two Medals of Honor, checked his rifle one final time. Ahead lay Belleau Wood—a tangled hunting preserve of ancient oaks, dense undergrowth, and German machine gun nests that had been fortifying for days. At 5:00 PM on June 6, 1918, the 5th and 6th Marine Regiments rose from their positions near Château-Thierry and walked straight into a firestorm.

The Germans couldn't believe what they were seeing. American troops—many of them former clerks, farmers, and factory workers who had been civilians just eighteen months earlier—advanced in textbook formation across open ground, as if the lessons of Verdun and the Somme meant nothing. Machine guns from the 461st Imperial German Infantry Regiment opened up at 400 yards. Marines fell in waves. In that single afternoon, the Corps suffered 1,087 casualties—more than in its entire previous 143-year history combined.

Yet they kept coming.

What followed was three weeks of close-quarters savagery that would permanently alter America's role in the Great War. The fighting devolved into hand-to-hand…

💡 The battle's first day produced more Marine casualties than the Corps had suffered in its entire 143-year history up to that point.
