Barnet (Wars of the Roses).
Fought April 14, 1471, between the Yorkists under Edward IV, and the Lancastrians under the Earl of Warwick. Warwick prepared to attack the king as he issued from Barnet, but Edward came out during the night and took up a position opposite Warwick unseen. The left of the Yorkists was outflanked and beaten, but their right outflanked and defeated the Lancastrian left, and then fell upon and routed the centre. Warwick was slain. The losses on the two sides are said to have amounted in all to 1,000 killed.
