I’ve written about my grandfather’s brother, Tom Dugan before, and mentioned his experience as a sailor on the USS Borie in World War II. The Borie was a WW I era destroyer pressed into service escorting convoys in the early days of the war, and it fought the most desperate and close-quarters battle with a U-Boat I’ve ever heard of. The History Guy does a good job of finding stories like this to feature, and he just released this video explaining the battle.
