At the time of the battle there was no bridge across the Boyne at Oldbridge, but there was a small village at approximately this point.
Two Jacobite infantry regiments lined up behind the houses and surrounding ditches, but their musket fire failed to halt the advance of King William's infantry across the river.
When William's Dutch Guards gained the south bank, they rushed to the attack, firing musket volleys and driving the Jacobites back."The action was so hot till past eleven that many old soldiers said they never saw brisker work".
Futher downstream, several more regiments of William's infantry crossed the river and managed to establish themselves on the south bank, where they drew up in battle formation to meet James's counterattack.
