In early November 1942, American and British forces stormed ashore in French-ruled Morocco and Algeria, beginning a campaign to press the Axis into a small bridgehead around the ports of Tunis and Bizerte in Tunisia. The U.S. Army had its first exposure to combat in the European Theater, while fresh British forces joined the veteran Eighth Army against the Axis. French troops fought first against the Allies, then with them. Inside the shrinking perimeter, German and Italian units continued to offer fierce resistance. 

An Army at Dawn is a complete boxed game in the Panzer Grenadier series based on these battles. You do not need any other game to play any of its 40 scenarios.
