On 20 July the Scots, more than 4,000 strong and commanded by Major-general James Holborne advanced against the English force of approximately 4,000 men. After a ninety-minute hiatus the cavalry of both forces engaged on each flank. In both cases the Scots initially had the better of it, but failed to exploit their advantage, were counter-charged by the English reserves, and routed. The previously unengaged Scottish infantry attempted to retreat, but in a running battle lost heavily in dead and captured.
