26 June, 1918

BGen James G. Harbord, the Commanding General of the 4th Marine Brigade, notified American Expeditionary Force Headquarters that Belleau Wood was "now U.S. Marine Corps entirely." After 20 days of combat, and at a cost of over 4,000 casualties, the 4th Brigade of Marines had proven its fighting heart. The grateful Commander of the French Sixth Army would soon decree that in all official correspondence, Belleau Wood would henceforth bear the name, "Bois de la Brigade de Marine."
