For the most part, the US Army's dominating battle tactic was what can be called the "turning movement". As used in the Mexican-American War it consisted of sending a detachment of forces away from the front lines and then attack the enemy's flank, causing panic and a retreat. Battles such as Monterrey and Cerro Gordo are examples of this tactic.
