War at Sea

From BoardGameGeek:

War at Sea is a simple, strategic wargame covering the Battle of the Atlantic and naval warfare in the Mediterranean in WW2. The game divides the contested seas into 6 areas. Each turn the players move their ships from home ports to one or more of the areas. After all ships have been moved a battle occurs. After a number of rounds, until one side or the other retreats or loses all of his/her ships, the player with ships left takes control of the area and scores a number of "Points of Control (POC)". If German U-boats survive anti-submarine combat they may stay in the area, even if the area contains Allied ships, and prevent the Allies from controlling the area and scoring points for it. The Allied player has the additional challenge of escorting convoys across the Atlantic. Any that reach England score one POC. If one reaches Russia it scores a BIG three POCs. Avalon Hill
