American forces weren’t alone in launching assaults on the last day. The British high command, still stinging from its retreat at Mons during the first days of the war in August 1914, judged that nothing could be more appropriate than to retake the city on the war’s final day. British Empire losses on November 11 totaled some twenty-four hundred. The French commander of the 80th Régiment d’Infanterie received two simultaneous orders that morning: one to launch an attack at 9 a.m., the other to cease fire at 11. Total French losses on the final day amounted to an estimated 1,170.
The Germans, in the always-perilous posture of retreat, suffered some 4,120 casualties. Losses on all sides that day approached eleven thousand dead, wounded, and missing.

Indeed, Armistice Day exceeded the ten thousand casualties suffered by all sides on D-Day

note: this doesn’t cover American deaths of about 300
