The assault troops were formed of three American divisions of the VI Corps, reinforced with a French armoured division. The 3rd Infantry Division landed on the left at Alpha Beach (Cavalaire-sur-Mer), the 45th Infantry Division landed in the centre at Delta Beach (Saint-Tropez), and the 36th Infantry Division landed on the right at Camel Beach (Saint-Raphaël). At Cap Negre, on the western flank of the main invasion, a large group of French commandos landed to destroy German artillery emplacements (Operation Romeo). These were supported by other French commando groups landing on both flanks, and by Rugby Force, a parachute assault in the LeMuy-Le Luc area by the 1st Airborne Task Force: British 2nd Independent Parachute Brigade, the U.S. 517th Parachute Regimental Combat Team, and a composite U.S. airborne glider regimental combat team formed from the 509th Parachute Infantry Battalion, the 550th Glider Infantry Battalion, and the 1st Battalion, 551st Parachute Infantry Regiment(Operation Dove). The 1st Special Service Force took two offshore islands to protect the beachhead (Operation Sitka). Operation Span, a deception plan, was carried out to shield the main invasion.
Naval gunfire from Allied ships, including the French battleship Lorraine, British battleship HMS Ramillies, and the American capital ships USS Texas, Nevada and Arkansas and a fleet of over 50 cruisers and destroyers supported the landings. Seven Allied escort carriers provided air cover.
Over ninety-four thousand troops and eleven thousand vehicles were landed on the first day. A number of German troops had been diverted to fight the Allied forces in Northern France after Operation Overlord and a major attack by French resistance fighters, coordinated by Captain Aaron Bank of the OSS, helped drive the remaining German forces back from the beachhead in advance of the landing. As a result, the Allied forces met little resistance as they moved inland. The quick success of this invasion, with a twenty-mile penetration in twenty-four hours, sparked a major uprising by resistance fighters in Paris.
Follow-up formations included U.S. VI Corps HQ, U.S. Seventh Army HQ, French Army B (later redesignated the French First Army) and French I and II Corps, as well as the 51st Evacuation Hospital.
