In March 1942 she was lent to the U.S. Navy, but still manned by a British crew, to assist the American`s newly formed anti-submarine forces. In October 1942 she was returned to R.N. control and in December Hertfordshire was transferred to South African waters to combat the growing U-boat threat in this area. From February 6-12th 1943 she was docked in the Selborne dry dock at simonstown, South Africa and spent the rest of the war escorting convoys around the South African coast. In 1945 Hertfordshire returned to U.K. waters. She was sold later in 1945. |
