Following the war O'Doherty continued in his loyalty to the Crown but in 1608, after a dispute with the new Governor of Derry, O'Doherty rose in revolt with the castle as his headquarters. The Burning of Derry in April triggered what became known as O'Doherty's Rebellion. In response the Dublin authorities sent troops to overrun O'Doherty's Inishowen heartlands. After a siege they captured Burt Castle and freed the prisoners taken at Derry who were being held there. Shortly afterwards O'Doherty was killed at the Battle of Kilmacrennan and the rebellion collapsed.
