This is a IABSM game based on the Surprise Encounter scenario from Chris Stoeson's Campaign for Greece 1941 booklet. It takes place in North Greece on April 10, 1941.
A party of Royal Engineers is tasked with blowing bridges along the expected German invasion route and are then attacked by German recce units. Unknown to the players, it is a two-part game. If the British escape from the Germans, the table is reversed, a village added to the new Southern edge and the engineers get to attempt to destroy another bridge. Martin played the Brits and NZ armored car troop, and I was the German player.
