"I-29" left for Europe in November. Arriving off the Spanish coast on March 10, 1944, she and her escort of four torpedo boats and eight Junkers Ju 88s came under attack from Allied Coastal Command Mosquitoes and Liberator bombers. She survived the attack and arrived in Bourdeaux. She was sunk on her return journey in the Bashi Channel of the south coast of Taiwan on July 26 by the submarine USS "Swordfish".
