His escape coincided with the arrival of Sir Cahir O'Doherty in Dublin to clear up a misunderstanding in which it had mistakenly been believed O'Doherty had been plotting an uprising. Delvin's escape shattered the government's confidence even in loyal Gaelic lords like O'Doherty, who were suspected of being part of a conspiracy with Delvin and others. The following year an aggrieved O'Doherty and his followers burnt the town of Derry, thus launching O'Doherty's Rebellion.
