Dynamo: Dunkirk, 1940 is a strategic/operational-level simulation of the decisive middle phase of the battle for France. The first phase ended when the tanks of Panzergruppe Kleist emerged unscathed from the western end of the Ardennes Forest on 14 May, thus unhinging the entire Allied strategic plan. The third phase began on June 5, when the final drives into the heart of France were begun.
