Massue, Lanier, Langston and Byerley also crossed the causeway, attacking Dorrington's flank. Most commentators, even those sympathetic to William, judged that the Irish foot had fought exceptionally well, and some accounts including James II's Memoirs claim that Saint-Ruhe was "in a transport of joy to see the foot [...] behave themselves so well". Appearing to believe that the battle could be won, he was heard to shout, "they are running, we will chase them back to the gates of Dublin", before riding across the battlefield to direct the defence against the Williamite cavalry on his left wing. However, as he rode over to rally his cavalry, Saint-Ruhe paused briefly to direct the fire of a battery, and was decapitated by a cannonball; his death was said to have occurred around sunset, shortly after eight o'clock. After Saint-Ruhe's death the Jacobite left, devoid of a senior commander, collapsed very quickly: the regiment of Horse Guards left the field almost immediately, followed shortly by the cavalry and dragoon regiments of Luttrell, Sheldon and Galmoy. De Tessé attempted to head a cavalry counter-attack but was seriously wounded shortly afterwards. The Jacobite left flank was now exposed: Mackay and Tollemache also attacked again in the centre, pushing the Jacobites towards the hilltop. Burke and his regiment, still holding the castle, were forced to surrender. Most of the infantry remained unaware of Saint-Ruhe's death, however, and Hamilton's infantry on the Jacobite right continued to counter-attack, fighting the Huguenot foot to a standstill in an area still known locally as the "Bloody Hollow". At around nine o'clock towards nightfall the Jacobite infantry were finally pushed to the top of Killcommadan hill and broke, fleeing towards a bog in the left rear of their position, while their cavalry retreated towards Loughrea. Sarsfield and Galmoy briefly tried to organise a rearguard action but as in many battles of the period, most of the Jacobite casualties occurred in the pursuit, which was ended only by darkness and the onset of mist and rain. The defeated infantry were cut down in their hundreds by the Williamite cavalry as they tried to get away, many of them having thrown away their weapons in order to run faster. In addition to the rank and file the Jacobite casualties and prisoners included many of its most experienced infantry officers: the dead included brigadiers Barker, O'Neill and O'Connell, and colonels Moore, Talbot, O'Mahony, Nugent,
