From a trip to Normandy in 2003- This is inside a German bunker on the hill above Omaha beach. The graphiti here i would presume would be left by a soldier, although you can't be sure (26th Panzer Division?) Since soldiering involves waiting for hours and hours, graphiti was in most bunkers. One of the most cherished and preserved is in the tunnels under vimmy ridge, where soldiers waited all night to attack. One of the soldiers carved an elaborate maple leaf into the rock, before it was our flag.
