The enemy made an unsuccessful attempt to ram. No one manned the Japanese ship's machine gun atop her pilot house; her top deck was in shambles; and the ship was dead in the water but not sinking. ''Spot'' waited for an hour and then sent over a boarding party of seven men to plant demolition charges and search for intelligence material. After about ten minutes on board, the party had to abandon as the ship listed to port and sank by the stern. The boarding party was recovered and one Japanese prisoner taken.

''Spot'' was surfaced and heading for deeper water but could not elude one of the escorts, the minesweeper ''W-17'', which closed to and opened fire. ''Spot'' manned her guns and returned the fire even though she was wallowing heavily in the rough seas. A lucky hit by her gun knocked out ''W-17'''s forward gun and saved the submarine from almost certain disaster. ''Spot'' secured her guns, cleared the bridge, and submerged. The escort dropped a few depth charge patterns which caused no damage, and the submarine returned to Saipan on 23 March to reload. On 27 March 1945, ''Spot'' resumed her patrol.
