Soon after 08:45 on 8 June, she was ordered by the Commander of Task Group 125.8 (TG 125.8) aboard "Tuscaloosa" to Fire Support Area 3 to assist the destroyer which had struck a mine northwest of the Saint-Marcouf Islands. "Rich" proceeded at full speed to the area, and then followed in the wake of two minesweepers to the immediate area of the "Glennon". Closing "Glennon", "Rich" dispatched a whaleboat, only to learn that her assistance was not needed at that point. "Rich" then started to round the disabled ship and take up station ahead of the minesweeper which had taken "Glennon" in tow. She moved at slow speed, with extra hands on the lookout for enemy planes and mines.
