Great uncles, on my mother's side of the family, and uncle, on my dad's side.
On Mom's side...
My uncles Jimmy and Bernie Tognoli were in the Navy, both Seabees, in the Pacific. They were steelworkers, and I think that was a big reason they were assigned to construction
My Uncle Cajetan Fonzone was in the Army Air Force, tried for pilot training, but washed out when it was found he was a sleepwalker. He was trained then as an electrical engineer and was in the 20th Air Force in the Pacific
My uncles Eddie Tognoli, Mike Fonzone and Nicky Fonzone served, too, but I'm not sure which branch of the services. I think they were all in the Army, in Eurpoe
My Uncle Kermit Trout lied about his age to enlist in 1942 (he was just a little younger than his friends, and he wanted to go when they enlisted). After boot camp, he was going to be assigned as a medic, but he asked his company CO if he could join a rifle company instead, because, as he put it, he couldn't stand the sight of blood. I don't know his unit, but he was in the second wave at Omaha, and eventually wound up in the 3rd Army, and survived the whole campaign, ending up in a town in Bavaria, where he shinnied out on a flag pole from a window to cut down a swastika flag as a souvenir. He was wounded twice and received the Purple Heart twice, and was awarded 2 Bronze Stars and a Silver Star. Those details, we didn't generally know, because he never mentioned them. It wasn't till he passed away, that I learned of the awards. Uncle Kermit liked to tell about things he remembered as funny.
On Dad's side, his older brother, my Uncle Bill, turned 18 in 1945, and was drafted out of high school and into the Navy. He was a Seabee, too, and worked on building the runways at the airfields in the Marianas.
