In the summer of 1520 Albany went to Rome. The Master of Papal ceremonies took offence when Albany arrived at the Vatican during Vespers and sat with the Cardinals on Ascension Day. He made Albany get up, and while waiting for the Pope, Albany sat on a Cardinal's foot-stool. Subsequently, the Cardinal of Ancona formally presented Albany's request for an audience with the Pope, as the guardian of James V. Pope Leo issued a new bull confirming his protection of Scotland and James V and affirming Albany's regency. Albany returned to Scotland in November 1521. In November 1522, Albany took an army to besiege Wark Castle defended by Sir Sir William Lisle, but gave up after three days when the weather deteriorated.
