McVay's orders were to "zigzag at his discretion, weather permitting"; however, McVay was not informed that a Japanese submarine was operating in the vicinity of his route from Guam to Leyte. Further, Mochitsura Hashimoto, commander of I-58, testified that zigzagging would have made no difference.[32] Fleet Admiral Chester Nimitz remitted McVay's sentence and restored him to active duty. McVay retired in 1949 as a rear admiral.[33]
