Faenza (First Gothic War).
Fought 541, between 20,000 Roman legionaries, and the Goths under Totila, King of Italy. The Romans made no attempt to resist the onslaught of the Goths, but throwing down their arms fled ignominiously, giving the Goths an easy victory.
Fair Oaks (American Civil War).
Fought May 31, and June 1, 1862, between the Federals under General M’Clellan and the Confederates under General Johnston. M’Clellan was advancing upon Richmond, and his left wing was attacked in the afternoon of the 31st, and notwithstanding the arrival of Sumner's corp in support, was driven back for two miles. On the 1st the Federals recovered the ground they had lost, but made no further progress, and at the end of the day the Confederates, who were largely outnumbered, were permitted to retire unmolested. The Federals lost over 7,000 killed and wounded, the Confederates about 4,500, including General Johnston. This is also called the Battle of Seven Pines.
