Vice President Mike Pence will attend the National D-Day Memorial’s 75th anniversary commemoration of D-Day to deliver the keynote address.

The ceremony is being hailed as possibly the last opportunity to recognize some of the last remaining veterans who served on June 6, 1944.

More than 60 World War II veterans will attend the commemoration at the National D-Day Memorial. Of those, 30 participated in the D-Day invasion of Normandy.

With the youngest World War II veterans in their mid-90s, organizers titled this commemoration as “The Final Salute: D-Day plus 75 years” to assure those who served are recognized one last time.

“The name was selected as the 75th anniversary represents perhaps our last, best opportunity to thank many of these veterans personally,” said Angela Lynch, associate director of marketing for the memorial.

Attendance is expected to be the largest — as many as 20,000, Lynch estimated — at the memorial since its dedication in 2001 when President George W. Bush attended.

Programs and activities are planned throughout the week to commemorate the anniversary, starting June 5 at 3 p.m. with the dedication of a U.S. Naval Academy plaque.

Multiple events are scheduled at the memorial, in the town of Bedford and Lynchburg through June 9.

On June 6, the National D-Day Memorial’s program will begin at 10 a.m. with an aerial tribute to World War II veterans, followed by the commemorative observance with Pence at 11 a.m.
