The story
In autumn 1689 Schomberg’s Williamite army halted at Dundalk, facing the forces of James II. Poor supplies, inexperienced troops and sickness undermined the campaign. The army eventually withdrew to northern winter quarters. Disease made this episode disastrous even without the decisive battle its commanders had expected, showing how weather, shelter, food and health could determine a campaign as much as military tactics.↗1↗2
A contemporary plan in the Royal Collection records the camp from 7 September into November. Its key identifies the town, bridge, regiments, artillery, trenches and opposing scouts. Read beside the written histories, the map makes Dundalk’s strategic setting visible at a particular moment. The following year William took personal command and advanced to the Boyne; the failed Dundalk season belongs to the same war, but has its own distinctive human story.↗1↗2
