Early success
On the Allied invasion of France, following the D-Day landings ...
... by the end of the day, 150,000 men had managed to get ashore, and a firm foothold had been established for the cost of 2,500 dead.
In spite of the considerable success achieved on D-Day, the Allies had to create a beachhead swiftly, and then conduct breakout operations, if they were to take full advantage of their position.
