D-Day Veterans — Normandy

We are conducting a survey to determine how many American D-Day veterans are currently known to be living.

Our organization is presently aware of twenty-three Normandy (with arrowhead) World War II veterans who served in the June 6, 1944, D-Day landings and whose military DD-214 discharge papers indicating participation in the operation.

FYI: For the Normandy invasion (D-Day, June 6, 1944), soldiers, sailors and airmen who took part in the initial amphibious landings, airborne jumps, or glider assaults could receive the Arrowhead on the Normandy landings campaign medal. Without it, they did not serve in the D-Day operation.

If you know of any American D-Day veterans, please contact lets us know.

Remembering those we lost on the USS Indianapolis, July 1945

On this Memorial Day, we remember the 888 crewmen of USS Indianapolis who never came home.

From the 9 men lost in the kamikaze attack on March 31, 1945, to the 879 sailors and Marines lost after the sinking on July 30, 1945, their sacrifice will never be forgotten.

They were only boys and young men to many who loved them. Sons. Brothers. Husbands. Fathers. Friends. Their lives, their sacrifices, and their stories deserve to be remembered, not just today, but always.

In the comments below, we invite you to share the names and photos of your own loved ones who gave their lives in service to our country, so that together, we may honor and remember them this Memorial Day weekend. 🇺🇸
