For the next year and a half, the squadron tooj part in some 348 escort missions, involving 750 ships and covering over 240,000 nautical miles. The squadron quickly earned such an excellent reputation for smart shiphandling that the Royal Navy eventually turned over two of its destroyers to be manned by Japanese crews for the duration of the war. The Japanese contingent was even blooded duing the Mediterranean campaign. One destroyer, Sakaki, was torpedoed and lost 59 officers and men, including her skipper, but made it back to Malta and eventually rejoined the squadron.
