The Royalist army led by Lord Digby and Marmaduke Langdale had been trying to force a passage north to link up with the Marquis of Montrose. The battle took place on 20 and 21 October 1645 when the experienced cavalry commander Sir John Brown of Fordell and his newly raised Scots cavalry regiment defeated the Royalists army. The Royalists lost more than half of their 600 men as casualties or prisoners. The remainder of the Royalist were driven back into England.
