On their left centre, the Williamites advanced across low ground exposed to Jacobite fire and took a great number of casualties. The Williamite assault in this area, led by St John's and Tiffin's regiments and the Huguenot foot, was driven back into the bog by the Irish foot fighting with clubbed (reversed) muskets; many of the attackers were killed or drowned.Hayes-McCoy, pg. 24 In the rout, the pursuing Jacobites managed to spike a battery of Williamite guns. The Jacobite regiments of the Guards and Gordon O'Neill were said to have fought particularly strongly. The musketry was so intense that "the ridges seemed to be ablaze" according to Andreas Claudianus, a Norwegian fighting with the Danish infantry.
