A secure area at the end of a bridge that is held by troops to protect it from the enemy and to allow for further military operations.
The soldiers established a bridgehead to launch their attack into enemy territory.
Bridgehead → It is formed from "bridge" (from Old English "brycg", meaning a structure built to span a physical obstacle) and "head" (from Old English "heafod", meaning the top or front part). The term "bridgehead" refers to a fortified position established on the enemy's side of a river or other obstacle, serving as a base for further operations.
Think of a 'bridge' as a structure that spans an obstacle and a 'head' as the top or front part — a bridgehead is a strong position established on the other side of a barrier.
