    YMS-48 101k 7 July 1942 Joe Radigan
    YMS-8 279k YMS-8 and YMS-48 cleaning a pathway through the mines off Bataan peninsula, these hardy little minesweepers can work under severe Japanese coastal bombardment. Despite Army air cover overhead, the enemy shore guns sank the motor minesweeper YMS-48 and damaged the destroyers Fletcher [DD-445] and Hopewell [DD-681]. On the following day, a naval task group landed Army troops on the peninsula and a short time thereafter resistance ceased on Corregidor and Bataan
