Returning to the places where they once served often allows military veterans to heal from the emotional traumas they experienced during war. That’s why, since Denver resident Timothy Davis started the Greatest Generations Foundation (TGGF) 15 years ago, the nonprofit has helped more than 6,000 former service members complete pilgrimages to sites like Pearl Harbor and Iwo Jima as well as battlefields in Vietnam. “We have a responsibility to honor the sacrifices these veterans made to serve our country,” Davis says. This month, TGGF will send 62 U.S. veterans of World War II back to Normandy, France, for the 75th anniversary of D-Day, when the Allied Forces invaded continental Europe on June 6, 1944. Thirty members of the group will travel aboard the Queen Mary II, an ocean liner that was used to transport troops during the war. Seven more will fly to France on Air Force One with President Donald Trump. And another 25 have been given funds to book trips for themselves and their families. This time, instead of charging into battle, the veterans revisiting the beaches and stone-walled villages of Northern France will be honored by world leaders for the actions they took to, as President Franklin Roosevelt put it, “set free a suffering humanity.”
