The Battle of San Jacinto in 1836, during the Texan Revolution. Texan soldiers were infuriated by the Mexican victory at the Alamo and the cold-blooded massacre of James Fannin and his men at Goliad shortly after.
I think the Battle of the Bloody Angle at Spotsylvania Courthouse and the Battle of Crater at Petersburg are two American Civil War battles in which one or both sides were fuelled by murderous hatred of the foe. At the Crater Confederate troops were doubly enraged by the Union's usage of a mine and of African-American troops; supposedly Robert E. Lee himself turned a blind eye to the murder of captured black soldiers after the battle.
