After their retreat from the Boyne, both wings of the
Jacobite army converged on Duleek to avoid being trapped in a pincer
movement by King William's army.
The bridge at the time was only half its present width, and many
soldiers must have waded through the river Nanny. The French infantry
brigade covered a confused retreat and Jacobite casualties were
comparatively light. Subsequently the army was able to regroup west of
the Shannon to continue the war.
