First Battle of Hoover Dam

The First Battle of Hoover Dam is the name of Caesar's Legion's attack on New California Republic forces stationed at Hoover Dam.

Background
The NCR Army faced the Legion in 2277. Windstorms in the Divide caused delays to NCR reinforcements and supplies before the battle. The NCR was led by Chief Hanlon, who commanded the First Recon, Bravo Company, and Lee Oliver's troops. Under the command of the Malpais Legate, the Legion forces marched against the New California Republic at Hoover Dam, in an attempt to take the strategic asset and Colorado River crossing. The Malpais Legate was unable to penetrate the Republic's defenses.

The NCR First Recon and NCR Rangers executed a tactical retreat west into Boulder City after using their prowess in marksmanship to kill the Legion's veterans from afar, an act that prompted the Malpais Legate to order the Legion's elite forces to push forward in pursuit of the enemy sharpshooters.

The Legate realized too late that the Rangers and First Recon had booby-trapped Boulder City, laying explosives all along their route of retreat and throughout the city itself. When the Legion's elite forces entered the city, the Rangers and First Recon detonated the explosives and inflicted severe casualties on the enemy, crippling their offensive. Shortly after the few survivors of the trap at Boulder City were destroyed, NCR Troopers under the command of General Lee Oliver counter-attacked, pushing back and eventually routing the Legion's main force after having successfully held the dam.

Appearances
