Hubert Paul Chatelain , born in Mansura, La., 11 February 1917, enlisted in the Navy 10 July 1935. As gunner's mate first class serving in South Dakota (BB-57), Chatelain was killed in action 26 October 1942 during the Battle of Santa Cruz. For his great bravery as captain of a 40mm. mount during the battle, he was posthumously awarded the Silver Star Medal.

  Chatelain (DE-149) was launched 21 April 1943 by Consolidated Steel Corp. of Texas, Orange, Tex.; sponsored by Mrs. L. T. Chatelain ; commissioned 22 September 1943, Lieutenant Commander J. L. Foley in command; and reported to the Atlantic Fleet.

Destined to play an important part in sweeping the Atlantic of German submarines, Chatelain escorted two convoys from east coast ports to Londonderry and Gibraltar between 20 November 1943 and 7 March 1944, and was then assigned to operate as part of the hunterkiller group formed around Guadalcanal (CVE-60).

During the last year of the European war, while operating with the Guadalcanal group, Chatelain joined in the sinking of two German submarines, and the capture of a third. Her first action took place 9 April 1944, as her group sailed from Casablanca to the United States. U-515 was detected when her radio transmissions were picked up, and planes and ships of the task group pressed home a firm attack. Chatelain forced the enemy submarine to the surface with two depth charge attacks, then joined in the general firing at point-blank range which followed, sending U-515 to the bottom in 34°35' N., 19°18' W.

On 4 June 1944, Chatelain had the distinction of initiating one of the most dramatic incidents of the war, when she made a sound contact, and hurled a barrage of hedgehogs at a U-boat. A second attack by Chatelain , this time with depth charges, holed U-505's outer hull and forced her to surface, her crew jumping overboard as she broke water. Now, the task group seized its chance to carry out the boarding operation, it had been planning for months, for the first capture by Americans of an intact German submarine. Successful in taking control of the submarine and executing the damage control that made its towing practicable, the group was awarded the Presidential Unit Citation for this action.

In one of the last antisubmarine actions of the Atlantic war, Chatelain took part in a 12-hour hunt for the submarine which had torpedoed Frederick C. David 24 April 1945. Eight other ships joined her as the group again and again attacked U 546, sinking her finally in 43°53' N., 40°07'W.

Chatelain had patrol and convoy escort duty, as well as serving as plane guard during aviation exercises, until 20 November 1945, when she arrived at Charleston, S.C. She was decommissioned and placed in reserve at Green Cove Springs, Fla., 14 June 1946.

In addition to the Presidential Unit Citation, Chatelain received five battle stars for World War II service.
