8-1. On 21 April 1943, while operating off the Malay Peninsula during her sixth war patrol, GRENADIER sustained heavy damage to the after portion of the ship as the result of a Japanese aircraft depth bomb attack. The most serious casualty which occurred, and which directly caused GRENADIER'S loss, was the complete immobilization of her propulsion plant due to derangement of the main control cubicle and severe misalignment of the propeller shafting. All efforts by ship's force to effect emergency repairs were unsuccessful. Early the next morning, GRENADIER was abandoned and scuttled by her own crew to prevent imminent capture by an approaching Japanese merchant ship.
