Teachers and school administrators from the Baltimore area greet Rear Adm. Brad Williamson, commander, Standing NATO Maritime Group 2, Cmdr. Bryan Carmichael, commanding officer, USS Oak Hill, and Cmdr. Orlando S. Bowman, executive officer, USS Oak Hill, during a visit aboard the dock land ship USS Oak Hill. The visit is part of ship tours during the celebration of the bicentennial Battle of Baltimore which provided the inspiration for Francis Scott Key's famous poem, "Defence of Fort McHenry," which later became America's national anthem. Along with more than 30 ships from the U.S. and foreign nations, the U.S. Navy's Blue Angels aircraft will be on display and open to the public.
