The goal for the first 40 days was to capture Caen and Cherbourg (especially Cherbourg, for its deep-water port). Then Brittany and its Atlantic ports would be captured. Railways and roads in northern France would be bombed to block reinforcements for the defenders. Next, the Allies would go 125 miles (190 km) to the southwest of Paris. The Allies would then control the land between the rivers Loire in the south and Seine in the northeast.
