insufficient capacity to handle Allied supply needs and French generals under Charles de Gaulle pressed for a direct attack on southern France with participation of French troops. These factors led to a reconsideration of the plan. Despite Churchill's objections, the operation was authorized by the Allied Combined Chiefs of Staff on 14July, then renamed Dragoon on 1August. The landing was scheduled for 15August. Churchill and his chiefs of staff had opposed Dragoon in favour of reinforcing the campaign in Italy, by capturing Trieste, landing on the Istria peninsula, and moving through the Ljubljana Gap into Austria and Hungary. Then on 4 August, Churchill proposed that Dragoon (less than two weeks away) should be switched to the coast of Brittany. Eisenhower, supported by Roosevelt, who (with his 1944 election campaign four months away) opposed diverting large forces to the Balkans, stood firm on the agreed plan despite long harangues from Churchill on 5 and 9 August. Planning The chief objectives of Operation Dragoon were the important French ports of Marseille and Toulon, considered essential to supply the growing Allied forces in France. The Allied planners were cautious, taking heed of lessons learned from the Anzio and Normandy landings. They chose a location with no high ground controlled by the Wehrmacht, conditions that had led to heavy casualties after the initial landings on Omaha Beach at Normandy. The choice for the disembarkation site was an area on the Var coast east of Toulon. A preliminary air campaign was planned to isolate the battlefield and cut the Germans off from reinforcement by destroying several key bridges. A large airborne landing was also planned in the center of the landing zone to quickly seize the high ground overlooking the beaches. Parallel to the invasion, several commando units were to take control of the islands off the coast. The Allied plan consisted of a three-division landing of US forces led by Major General Lucian Truscott to secure a beachhead on the first day. Their flanks were to be protected by French, American and Canadian commando units. Within 24 hours, 50,000–60,000 troops and 6,500 vehicles were to be disembarked. The airborne landings would concentrate in an area near Draguignan and Le Muy, with the aim of taking these towns to prevent German counterattacks against the beaches. The bulk of the American force then had to advance quickly to the north along the Rhône, to take Lyon
