The battle’s historical importance is evident in its legacy of Belleau Wood, symbolizing Marine Corps heroism and the turning point in the 1918 military campaigns.
When Was the Battle of Belleau Wood?
The Battle of Belleau Wood took place from June 1 to June 26, 1918, during the height of World War I’s Spring Offensive on the Western Front. This 26-day battle occurred near the Marne River in France, as part of the larger Aisne offensive where German forces aimed to break through to Paris. The engagement began with U.S. Marines relieving French troops and launching attacks on June 6, culminating in the wood’s clearance on June 26.

The timing was critical: Germany’s Spring Offensive, launched in March 1918, had initial successes but stalled by June, with the battle at Belleau Wood representing a desperate push to exploit a gap in Allied lines. American Expeditionary Forces under General John J. Pershing arrived in force that spring, with the battle marking one of their first major tests. Weather during the battle was hot and humid, with temperatures often exceeding 30°C (86°F), exacerbating fatigue and water shortages in the dense forest. Occasional rain turned paths muddy, complicating movements.
This period followed the Battle of Château-Thierry (May 31–June 3, 1918), where Americans first engaged, and preceded the Second Battle of the Marne (July 1918), where Allied counteroffensives turned the tide. The battle’s dates reflect the rapid American integration into the war, boosting Allied morale and signaling the end of German dominance.
Battle of Belleau Wood Map
A Battle of Belleau Wood map is indispensable for understanding the dense forest terrain that turned the battle into a grueling close-quarters combat affair. Historical maps, such as those from the U.S. Marine Corps University or Wikipedia, depict Belleau Wood as a 200-acre kidney-shaped forest near the Marne River, at coordinates approximately 49°04′N 3°17′E, in the Aisne department of France. The wood lies between the villages of Belleau to the east and Bouresches to the south, with open fields and ravines surrounding it.
Key features on typical maps include:
- Geographical Layout: The wood is shown as a thickly forested area with rocky outcrops, ravines, and underbrush, making movement difficult. Open wheat fields border the west and south, with the Belleau village and cemetery to the northeast. The wood’s interior features hunting paths and clearings, but dense foliage provided cover for German machine guns.
- Allied Advance Paths: Blue arrows illustrate U.S. Marine assaults: from the west on June 6, with the 5th Marines attacking from Lucy-le-Bocage toward the wood’s southern edge, and the 6th Marines from the north near Hill 142. Maps show phased advances, with routes converging on the wood’s center by June 26.
- German Defensive Positions: Red lines mark the German Army’s entrenched lines: bunkers, trenches, and machine-gun nests in the wood’s interior, with strongpoints at the northern and southern tips. The Germans held the high ground, with wire entanglements and pre-sighted artillery.
- Battle Phases: Color-coded zones depict D-Day assaults (June 6) on Hill 142 and Bouresches; repeated attacks (June 7–12) with heavy losses; and final clearance (June 13–26), including the 7th Infantry’s relief. Insets detail sub-fights like the wheatfield charge.

Summary Battle of Belleau Wood: A Detailed Chronicle of the Engagement
The Battle of Belleau Wood was a ferocious 26-day struggle that tested American mettle in World War I, with U.S. Marines launching repeated assaults against entrenched German positions in a dense forest. This very detailed summary covers the prelude, phases, key actions, and aftermath, drawing from historical accounts for depth.
Prelude: The Aisne Offensive and Marine Deployment (May–June 5, 1918)
Germany’s Spring Offensive, the third phase (Blücher-Yorck) launched May 27, 1918, broke through French lines near the Aisne River, advancing 30 miles toward Paris by June 3. French forces retreated in disarray, with Paris 50 miles away. Foch appealed to Pershing for American troops; the 2nd Division (including the 4th Marine Brigade) was rushed to the front.
The 4th Marine Brigade (5th and 6th Regiments, 6th Machine Gun Battalion) under Colonel Albertus Catlin arrived June 2 near Château-Thierry, digging in along the Paris-Metz road. Germans occupied Belleau Wood, a 1.6 sq km hunting preserve with boulders, ravines, and thick underbrush, ideal for defense. Nakagawa no, German commander Colonel Otto von Hartlieb had 1,200 men from the 237th Division in machine-gun nests.
Rupertus ordered “hold at all hazards”; Marines relieved the French June 5, preparing for assault.
Phase 1: Initial Attacks on Hill 142 and Bouresches (June 6–9)
At 3:45 a.m. June 6, the 1st Battalion, 5th Marines (Major Julius Turrill) attacked Hill 142, a wooded knoll northwest of the wood, to secure the flank. Advancing 800 yards across open fields under machine-gun fire, they captured the hill by 9 a.m., but at 50% casualties (19 officers, 450 men). Germans counterattacked but were repulsed.
At 5 p.m., the 3rd Battalion, 5th Marines (Major Benjamin Berry) and 3rd Battalion, 6th Marines (Major Berton Soper) assaulted the wood’s western face. Charging across a wheatfield under enfilade from Bouresches, Berry’s men reached the southern edge but were pinned, Berry wounded (arm nearly severed). Soper’s battalion gained the northern edge. Casualties: 1,087 in one day, highest in Marine history to that point.

June 7–8 saw consolidation; Marines cleared pockets with bayonets and grenades. On June 9, artillery bombarded for 14 hours (French 75mm guns), but the Germans held.
Phase 2: Repeated Assaults and Stalemate (June 10–15)
June 10: The 2nd Battalion, 6th Marines (Major Thomas Holcomb) attacked the wood’s center at 4:30 a.m., gaining 400 yards but halted by machine guns. Casualties heavy; Holcomb’s unit reduced to 200.
June 11: The 1st Battalion, 6th Marines (Major John Hughes) assaulted the northern bulge at 4 a.m., capturing it hand-to-hand but failing to link with southern gains. Germans counterattacked with gas, forcing masks in heat.
June 12: Heavy bombardment preceded attacks; the 5th Marines cleared southern pockets, but progress was slow. June 13: The 7th Infantry (Army) relieved exhausted Marines, but Rupertus insisted Marines finish.
June 14–15: Rest and reorganization; gas attacks caused 250 casualties.
Phase 3: Final Clearance and Victory (June 16–26)
June 16–24: Continuous bombardment; attacks resumed June 23 with the 3rd Battalion, 5th Marines capturing Bouresches after house-to-house, but wood assaults stalled.
June 25: Final push at 3 p.m.; the 5th Marines advanced under creeping barrage, clearing northern wood by nightfall. June 26: At 7 a.m., the 2nd Battalion, 5th Marines charged the remaining pocket, overrunning machine guns in 20 minutes. By 7 p.m., Rupertus signaled “Woods now U.S. Marine Corps entirely.”

Aftermath: Consolidation and Legacy
Germans counterattacked June 28 but were repulsed. The battle cost the 2nd Division 9,777 casualties, but it stopped the German push, earning Marines the “Teufel Hunden” (Devil Dogs) nickname from Germans. This chronicle illustrates the battle’s ferocity, with Marines’ bayonet charges and grenades clearing bunkers in a preview of Pacific island fighting.
Casualties of the Battle of Belleau Wood
