The tank landing ship was lost in action while in Royal Navy service 26 January 1944, when she struck a mine off Anzio, Italy.

The 83rd utilized 4.2-inch (110 mm) mortars firing either white phosphorus, smoke, gas, or high explosive shells.

With waves at 20 to 30 ft (6.1 to 9.1 m) and continued gale force winds, the LST was blown into a known mine field located around 12 mi (19 km) offshore.

[6] The order was given for the US Army personnel to abandon ship, however, only four life rafts were undamaged, so any floatable loose materials were thrown overboard to assist men that were already in the water.

Soon the minesweepers Pilot and Strive, along with LST-16, YMS-34, YMS-43, and other YMS craft joined in the rescue and were able to pull 150 survivors from LST-422 and LCI-32 from the storm tossed waters.
