Almost the first blow in the war between Scotland and England was a direct attack on the Bruces. On 26 March 1296, Easter Monday, seven Scottish earls made a surprise attack on the walled city of Carlisle, which was not so much an attack against England as the Comyn Earl of Buchan and their faction attacking their Bruce enemies. Both his father and grandfather were at one time Governors of the Castle, and following the loss of Annandale to Comyn in 1295, it was their principal residence. Robert Bruce would have gained first-hand knowledge of the city's defences. The next time Carlisle was besieged, in 1315, Robert the Bruce would be leading the attack.
