Apart from a brief period in home waters off the Scandinavian coast, Terrapin served in the Far East for much of her wartime career.

The Schwabenland was grounded at Sildeneset in Abelnes harbour to prevent her from sinking and the Wörth was towed to port.

She opened her career by bombarding Japanese installations at Gunung Sitoli (Nias Island), western Sumatra.

With the assistance of the American submarine USS Cavalla, she was escorted and returned to Fremantle, Australia.

After inspection Terrapin was declared a constructive total loss on return to harbour and was later scrapped in June 1946.
