Beachhead
A beachhead is a temporary line created when a military unit reaches a landing beach by sea and begins to defend the area as other reinforcements arrive.According to the D-Day Museum: The armed forces use codenames to refer to the planning and execution of specific military operations.Operation Overlord also began on D-Day, and continued until Allied forces crossed the River Seine on 19 August 1944.[1]Once an amphibious assault starts, victory tends to go to the side which can reinforce the beachhead most quickly.This is exemplified by the landing at Suvla Bay in the Gallipoli Campaign during World War I and the amphibious landing at Anzio (during Operation Shingle) as part of the Italian Campaign of World War II.
