A group of 12 World War II Marines ranging in age from 85 to 97 is stuck on the island of Okinawa, waging what could be their final fight to return to Iwo Jima to commemorate the 65th anniversary of their greatest victory.

The veterans group, the Greatest Generation Foundation, asked the military to help them get to Iwo Jima after a charter plane company that had volunteered to take them to the battle site canceled two weeks ago, Stars & Stripes reported.
