"..While Nimitz was a 22-year-old ensign in the Philippines and conning the destroyer Decatur, his ship ran aground on a mudbank. However, he successfully rescued a man overboard when the ship ran into the mudbank. Nimitz was court-martialed and convicted of hazarding a Navy ship and received a letter of reprimand.[4].."
IIRC, wasn’t the BB USS Missouri run aground off of VA in the 50’s...took several days for tugs to pull her off...
