Well, it's my understanding that my uncle took Ft. Monroe single handedly!
The story goes something like this… After the Japanese attack on Pearl Harbor there was a rush to volunteer for the military. I don't know if my uncle rushed or took his time but at length he found himself working in a unit called the OSS. All of his friends in the unit had foreign language skills but he did not. Consequently his friends were trained in covert operations and dropped by parachute behind enemy lines in occupied France. It was only a matter of time before these brave men were discovered by the Germans and shot as spies. Meanwhile, back home in the U.S. my uncle's superiors looked for something my uncle could do to support the war effort. It was decided that my uncle could test the defenses of various military installations To do this he would sneak into the fort, place sacks of flour attached to a small explosive device on cannons and anything else he found of interest. Then he would go to the commander of the fort and tell him that his fort had been compromised. If he timed it right, the explosions would add the necessary weight to my uncle's message to let them know they were going to be in trouble with their own superiors. On this occasion the explosions did not disappoint; and that's how my uncle single handedly too Fort Monroe during wartime.
I got this story second or third hand so I'm sure I got some things wrong; but for the most part this is what happened.
