Battle of Belleau Wood — June 1918
By the first week of June 1918, the German Spring Offensive had fractured Allied lines across northern France. French forces were falling back toward Paris. Exhausted divisions were pulling off the line. A French general, encountering Marine officers moving toward the front, reportedly told them to turn around — the situation was lost.
The Marines kept walking.
What followed in the wheat fields and limestone ravines of Belleau Wood would last twenty-six days. It would cost the 4th Marine Brigade more than 4,500 casualties. And it would produce a name the German military would use for the rest of the war: Teufelshunde. Devil Dogs.
The Ground Before the Fighting
Belleau Wood sits roughly fifty miles northeast of Paris, near the village of Bouresches and the town of Chateau-Thierry. In June 1918, it was a hunting preserve — dense with oak and undergrowth, cut through with ravines and boulders. On the maps, it looked small: roughly one mile long, half a mile wide.
It was not small.
The German forces defending the position had spent weeks fortifying it. Machine gun nests were layered in depth, sited to cover every approach across open ground. The wheat fields surrounding the wood offered no cover and no concealment. Any force moving across them would do so in full view of the guns.
On June 6, 1918, Marines crossed those fields anyway.
What the Maps Recorded
The tactical maps produced during and after Belleau Wood document the grinding, sector-by-sector nature of the fighting in a way no after-action narrative fully captures. The wood changed hands — or changed in contested status — repeatedly across the month. What reads as a single engagement in most history accounts was in reality a series of attacks, withdrawals, reinforcements, and renewed assaults against fortified positions that refused to yield.
This map shows what the men on the ground understood through blood and exhaustion: Belleau Wood was not a single objective. It was a network of interlocking defensive positions that had to be taken piece by piece, often at bayonet distance. The terrain features, road networks, and river contours recorded here provide a precise geographic view of why the casualty figures looked the way they did.
The 4th Marine Brigade — attached to the 2nd U.S. Division — entered the fighting with roughly 8,000 men. By the end of June, more than 5,000 had been killed or wounded. Individual companies that entered the wood at full strength emerged with fewer than a third of their men fit for duty.
The Cost
Among the key engagements documented on this map: the flank attacks north of Champillon village on the left, and the seizure of Bouresches on the right. Bouresches — a village at the wood's eastern edge — was taken on the night of June 6 by a small detachment of Marines who held it against repeated German counterattacks in the days that followed.
The Marines were stopped. They regrouped. They went back in. By the final days of June, when the last report came through confirming Belleau Wood secured, the 4th Marine Brigade had suffered more casualties in three weeks than the entire Marine Corps had sustained in its previous history combined.
Gunnery Sergeant Dan Daly — already a decorated veteran — rallied his men at the edge of the wheat field on June 6. First Lieutenant Clifton Cates, who would later become Commandant of the Marine Corps, sent a message from inside the wood reporting his position critically reduced but that he would hold. He held.
The Map's Place in Marine Corps History

Belleau Wood is frequently compressed into a single line in broader accounts of World War I — a footnote to the larger Allied counteroffensives that followed. The maps from June 1918 resist that compression.
The base map dates to 1912. The unit movements and front lines were added in 1940 — recorded by men who had studied the ground, reviewed the reports, and understood what had happened there. What this map preserves is not a clean narrative of advance and victory. It is the tactical landscape of an engagement that cost the Marine Corps more than any battle it had fought before, and that became the foundation of what the Corps understood itself to be.
For a family member whose relative served with the 5th or 6th Marines. For a family that has carried this battle in their history for a hundred years. This is what the ground looked like. This is where it happened.
The Battle Archives Belleau Wood map — the operational map of the 4th Brigade (Marine), 2nd U.S. Division — is printed on archival Hahnemühle paper using the giclée process, faithful to the original cartographic record of the engagement. It is available unframed or professionally framed and ready to hang.
