8, Nov 1943, BYMS 2072 was diverted to Beirut where she re-joined BYMS73 and embarked men and supplies bound for Leros. BYMS 2072 carried four army officers, forty-six troops and stores while BYMS 2073, carried three army officers and forty-five men of the Buffs and Signals.

The German Air Force had almost total control of the skies and the Royal Navy mainly operated at night.

11 Nov 1943, BYMS 2072 and 2073 arrived at Alinda Bay on the east coast of Leros and disembarked the urgently needed men and supplies. After taking cover throughout the next day, BYMS 2072 parted company with her sister ship BYMS 2073 to return to Alinda Bay with cables for the Army Signal Corps.

In early evening, as she approached Leros BYMS 2072 was attacked by the Luftwaffe. She took immediate evasive action, with four bombs narrowly missing her. Out of sight, and unheard above the noise of the ship’s engines, four German DO-217 bombers, armed with eight glider bombs, attacked.  

The 2074 experienced a direct hit on the port side. The explosion blew the port 20mm gun, its platform and two gunners into the sea.  As BYMS 2072 heeled over to 45 degrees the mast collapsed resulting in the loss of a third crewman and injury to another.

Following the distress message, the Royal Navy sent the motor launch ML-299 and motor torpedo boat MTB-315 to their aid. The commanding officer of motor torpedo boat MTB-315 piloted BYMS72 into the bay where the dead and wounded were removed.

BYMS 2073
British Yard Mine Sweeper


BYMS’s were built in the United States and transferred the Royal Navy under the Lend-lease Programme. “British Yard Mine Sweepers” are so called because they were built to the same design as the US Navy’s “Yard Mine Sweepers”.  

Crews for the BYMS’s would sail to the United States, often on the Queen Mary, which could sail unescorted because of her greater speed, to collect their vessel. They would then have the formidable task of sailing their small vessel back across the Atlantic Ocean, often in winter.
