During the Spanish-American War, George Dewey launched a surprise attack on the Spanish in Manila. This naval attack against the Spanish fleet occurred in 1898 at the start of the war, and the Spanish were defeated.
The battle that began during the early morning hours of January 31, 1968, was the Tet Offensive, a coordinated series of attacks by North Vietnamese and Viet Cong forces against South Vietnamese and U.S. military targets. Launched during the Tet Nguyen Dan, the Vietnamese Lunar New Year, the offensive aimed to surprise and galvanize the Vietnamese population against the South Vietnamese government and its American allies. Despite initial successes and widespread attacks across the country, the Tet Offensive ultimately ended in a military defeat for the North, but it significantly shifted public perception of the war in the United States.
The attack was no surprise - the two armies were confronting each other. Alexander wanted to defeat the Persian army to gain control of the Persian empire.
