Roosevelt signed the Anfa plan which provided for the creation of 8 motorized infantry divisions and 3 armoured divisions. Equipped with American materiel, the 1st and 5th Armoured Divisions formed part of the 1st French Army, commanded by General de Lattre de Tassigny, and the 2nd Armoured Division commanded by General Leclerc formed part of the 3rd American Army under the command of General Patton. These 3 major units played an active part in the French campaign and in the final victory.
