HMS Battler (D18)

USS Altamaha (CVE-6) (originally AVG-6) was an Attacker-class escort carrier that served during World War II as HMS Battler (D18) in the Royal Navy.

Pre-commission
She was laid down on 15 April 1941 as a C3-S-A1, a second replacement freighter, Mormacmail for Moore-McCormack Lines, Inc. Under Maritime Commission contract at Pascagoula, Mississippi, by Ingalls Shipbuilding, Hull 293. She also was purchased and converted prior delivery and on 7 January 1942 she was named Altamaha but the name was cancelled on 17 March 1942. She was launched on 4 April 1942; sponsored by Mrs. Phillip Seymour, wife of Captain Seymour. She was redesignated ACV on 20 August 1942. Acquired by the United States Navy on 31 October 1942, she was simultaneously transferred (via the Lend-Lease programme) to the United Kingdom on the same day. She was renamed HMS Battler and commissioned into the Royal Navy on 15 November 1942.

Design and description
There were eight Attacker class escort carriers in service with the Royal Navy during the Second World War. They were built between 1941 and 1942 by Ingalls Shipbuilding and Western Pipe & Steel shipyards in the United States, both building four ships each.

The ships had a complement of 646 men and crew accommodation was different from the normal Royal Navy's arrangements. The separate messes no longer had to prepare their own food, as everything was cooked in the galley and served cafeteria style in a central dining area. They were also equipped with a modern laundry and a barber shop. The traditional hammocks were replaced by three tier bunk beds, eighteen to a cabin which were hinged and could be tied up to provide extra space when not in use.

The ships dimensions were; an overall length of 492.25 ft, a beam of 69.5 ft and a height of 23.25 ft. They had a displacement of 11420 LT at deep load. Propulsion was provided by four diesel engines connected to one shaft giving 8,500 brake horsepower (BHP), which could propel the ship at 17 kn.

Aircraft facilities were a small combined bridge–flight control on the starboard side and above the 450 ft x 120 ft flight deck, two aircraft lifts 42 ft by 34 ft, and nine arrestor wires. Aircraft could be housed in the 260 ft by 62 ft hangar below the flight deck. Armament comprised two 4 inch DP,AA guns in single mounts, eight 40 mm anti-aircraft gun in twin mounts and twenty-one 20 mm anti-aircraft cannons in single or twin mounts. They had the capacity for up to eighteen aircraft which could be a mixture of Grumman Martlet, Hawker Sea Hurricane, Vought F4U Corsair fighter aircraft and Fairey Swordfish or Grumman Avenger anti-submarine aircraft.

Service history
Battler served in the Royal Navy from November 1942 until the end of World War II, serving for the most part as convoy escort in the North Atlantic and Indian Oceans. She travelled the globe extensively — USA, UK, Gibraltar, Malta, Salerno, Palermo, Suez, Aden, Cochin (India), Bombay, Sri Lanka, Mauritius, Madagascar, Seychelles, Maldives, Sydney and the Panama Canal.

In September 1943, Battler supported the allied invasion of Italy at Salerno. In March 1944, as part of force CS4, she helped to disrupt U-boat operations in the Indian Ocean when her aircraft guided destroyers onto the German supply ship Brake and two U-boats. Brake was destroyed by gunfire from destroyer HMS Roebuck (H95) and one of the U-boats was damaged by Battler's aircraft.

Battler was returned to the U.S. on 12 February 1946 and struck from the Naval Vessel Register on 28 March. She was sold on 14 May to the Patapsco Steel Scrap Co., Bethlehem, Pennsylvania and was subsequently scrapped.
