forces into Northern Italy. Despite and due to the rapid advance of the Allied forces in Italy in June–July 1944, after the liberation of Rome, the high allied command in Western Europe decided to take away from the Italian front the French Expeditionary Corps and the U.S. VI Corps, reassigned for landing in the South of France in support of the advance in the north of that country, and to liberate southern France, including the huge port complexes of Marseilles and Toulon, and bring into action the seven divisions of the French 1st Army (1st and 5th armored, 1st, 2nd, 3rd, 4th, and 9th infantry) that had been reequipped in French North Africa by the United States. The gap in the ranks of the U.S. Fifth Army caused by the withdrawal of seven divisions (three US Army, the 3rd, 36th, and 45th infantry divisions; and four French, the 1st, 2nd, 3rd, and 4th divisions) was filled in 1944-45 by five US Army (10th Mountain, 85th, 88th, 91st, and 92nd infantry divisions) and one US-equipped Brazilian Army division (the 1st). Additional replacements and service elements were provided by conversion of the US Army's 2nd Cavalry Division, which had arrived in the theater in 1944. In order to complicate the Allied ambitions in Italy, between October 1944 and March 1945, the available British forces were also weakened by breaking up the 1st Armoured Division because of a lack of replacements for 8th Army's casualties, and the withdrawal and deployment to Greece of two British infantry divisions (4th and 46th), the British-controlled 4th Indian Division, the British 23rd Armoured Brigade, the British 2nd Parachute Brigade, and the Greek 3rd Mountain Brigade. In addition, the Canadian I Corps and the British 5th Infantry Division were withdrawn and redeployed to northwestern Europe in
