Naval Battle of Casablanca

The Naval Battle of Casablanca was a series of naval engagements fought between American ships covering the invasion of North Africa and Vichy French ships defending the neutrality of French Morocco in accordance with the Second Armistice at Compiègne during World War II.[1] The last stages of the battle consisted of operations by German U-boats which had reached the area the same day the French troops surrendered.[note 1] Allied military planners anticipated an all-American force assigned to seize the Atlantic port city of Casablanca might be greeted as liberators. An invasion task force of 102 American ships carrying 35,000 American soldiers approached the Moroccan coast undetected under cover of darkness. French defenders interpreted the first contacts as a diversionary raid for a major landing in Algeria; and regarded the surrender of six Moroccan divisions to a small commando raiding force as a clear violation of French obligations to defend Moroccan neutrality under the Second Armistice at Compiègne.[6] An escalating series of surprised responses in an atmosphere of mistrust and secrecy caused loss of four U.S. troopships and death of 462 men aboard 24 French ships opposing the invasion.[7] {| class="toc" id="toc"

[edit] Background
Morocco was a colony of France at the time of World War II. The French government at Vichy had surrendered to Germany after the Battle of France, signing an Armistice with Nazi Germany. General Charles de Gaulle led French forces opposed to the surrender and to the Vichy government, continuing the war on the side of Great Britain and the Allies. The Vichy regime—which controlled Morocco—was thus officially neutral, but in practical terms the Armistice obliged Vichy to resist any attempt by France′s erstwhile allies to seize French territory or equipment for use against Germany. British forces had attacked the French at Mers-el-Kébir for refusing to surrender to them or join the Allies, leading to much ill-will between France and Britain. The U.S. government had previously recognized the Vichy regime as legitimate. Military planning for Operation Torch in 1942 emphasized American troops in the initial landing forces on the basis of intelligence estimates they would be less vigorously opposed than British soldiers.[8]

[edit] American forces
Troopship convoy UGF 1 left Chesapeake Bay on 23 October 1942 and was joined on 26 October by a covering force of battleships and cruisers sailing from Casco Bay and on 28 October by the aircraft carriers USS Ranger,  Sangamon ,  Suwannee ,  Chenango , and  Santee  sailing from Bermuda. These ships were screened by 38 American destroyers.[9] The resulting Task Force 34 (TF 34) included 102 ships for the invasion of Morocco under the command of Rear Admiral Henry Kent Hewitt aboard the flagship heavy cruiser USS Augusta. As TF 34 sailed, the British submarine HMS Seraph landed Major General Mark W. Clark near Algiers to meet with pro-American French military officers stationed in Algeria. French officers shared information about defensive arrangements; but the Americans did not share critical invasion details of timing, strength and distribution of forces.[10] No information was provided to key French leaders including Armed Forces Commander in Chief Admiral François Darlan, North African Commander in Chief General Alphonse Juin, or Moroccan Resident General Charles Noguès.[11] Casablanca from space.===[edit] French forces=== In 1942, Casablanca was the principal Vichy-controlled port on the Atlantic (all of France′s Atlantic coast having been occupied by Germany since 1940) and the most important Vichy-controlled naval base after Toulon. Naval gunners manned the El Hank coastal artillery battery of four 7.6 in (190 mm) guns and four 5.3 in (130 mm) guns; and one quadruple 15 in (380 mm) gun turret of the modern battleship  Jean Bart  was operational, although the battleship remained incomplete following escape from the Saint-Nazaire shipyards during the German invasion of 1940. One light cruiser, two flotilla leaders, seven destroyers (two already damaged by collision), eight sloops, 11 minesweepers, and 11 submarines were in port on the morning of 8 November.[12]

Most French personnel attending General Clark′s pre-invasion meeting were army officers. Information subsequently conveyed in pre-invasion contact with army personnel stationed in Morocco was interpreted as a request for recommendations. No pre-invasion contact has been documented with Vice Admiral Michelier, who commanded naval forces responsible for the defense of Casablanca. Admiral Michelier was not yet in the confidence of North African officers in contact with the Americans, since he had been a member of the Armistice Commission until assuming his Casablanca post less than a month before the invasion.[13]

[edit] Prelude
French defenders were placed on alert status when Algerian invasion convoys were detected passing through the Strait of Gibraltar.[14] Destinations remained unclear, and TF 34 remained undetected as it split into three groups on 7 November. Concealed by darkness, a northern group (six troopships and two cargo ships escorted by the battleship USS Texas, the light cruiser USS Savannah and six destroyers)[15] prepared to land 9,000 troops of the 60th infantry Regiment reinforced with 65 light tanks to seize the Port Lyautey airfield; and a southern group (four troopships and two cargo ships escorted by the battleship USS New York, the light cruiser USS Philadelphia and six destroyers)[16] prepared to land 6,500 troops of the 47th Infantry Regiment reinforced with 90 medium and light tanks near the phosphate port of Safi to cover the southern approaches to Casablanca, while the center group prepared to land the Casablanca occupation force of 19,500 troops of the 3rd Infantry Division[17] reinforced with 79 light tanks near Fedala 15 mi (24 km) northeast of Casablanca.[18] Naval coastal defense batteries flanked both ends of the Fedala landing beach with four 5.3 in (130 mm) guns at Point Blondin to the east and three 4 in (100 mm) and two 2.95 in (75 mm) guns in Fedala on the point sheltering the western end of the beach.[19]

Cressman identifies the three ships as the 1969-ton colonial sloop La Grandiere with second class sloops La Gracieuse and Commandant Delage. La Grandiere was about the size of a destroyer with three 14 cm (5.5 in) guns and a maximum speed of 15 knots. Jane's Fighting Ships refers to the second class sloops as 20-knot, 630-ton minesweepers armed with two 9 cm (3.5 in) guns.
