Burt Castle surrendered without a blow.
Wingfield immediately liberated the inmates, and sent Bishop Montgomery's wife to her husband, and Lady O'Dogherty, her infant daughter and sister-in-law, to Dublin Castle.

As for Sir Cahir, instead of going to Castle Doe, he resolved to cross the path of the English on their march to that place, and coming up with them in the vicinity of Kilmacrenan, he was shot dead by a soldier.

The death of the young chieftain spread panic among his followers, most of whom flung away their arms, betook themselves to flight, and were unmercifully cut down.

Sir Cahir's head was immediately struck off and sent to Dublin, where it was struck upon a pole at the east gate of the city.
O'Dogherty's country was now confiscated, and the lord deputy, Chichester, was rewarded with the greatest portion of his lands.

But what was to be done with the people?
In the first instance they were driven from the rich lowlands along the borders of Lough Foyle and Lough Swilly, and compelled to take refuge in the mountain fastnesses which stretched to a vast extent from Moville westward along the Atlantic coast.
