The Battle of Tadcaster took place during the First English Civil War on 7 December 1642, when a Royalist force attacked the Parliamentarian garrison of Tadcaster, Yorkshire, which was held by between 900 and 1,500 soldiers under the command of Ferdinando Fairfax, Lord Fairfax. Newcastle marched out of York on 6 December, and split his force of 6,000 into two; he took 4,000 infantry down the main York–Tadcaster road to attack the town from the east, while sending a deputy, the Earl of Newport, with a further 1,500 to circle around and trap the Parliamentarians by attacking from the north-west.
