Here’s a post on the Brookwood American Cemetery and Memorial, near Brookwood, Surrey, and about 28 miles southwest of London.
Here’s a photo taken in November 2009:
U.S. Army Reserve Soldiers stand at attention during a Veterans Day observance at the Brookwood American Military Cemetery on Nov. 8. The 7th Civil Support Command color guard participated in the event, which honored the 468 American servicemembers laid to rest here and the 561 Soldiers, sailors and Marines missing in action, or lost at sea with names inscribed on the Brookwood chapel wall.
