The king's brother, Nigel Bruce, was carried to Berwick, and was there hanged and beheaded.

Christopher Seaton and his brother Alexander, the Earl of Athole, Sir Simon Fraser, Sir Herbert de Moreham, Sir David Inchmartin, Sir John Somerville, Sir Walter Logan, and many other Scotchmen of noble degree, had also been captured and executed, their only offence being that they had fought for their country.

In the bay of Brodick was a castle occupied by Sir John Hastings and an English garrison.

The Scots concealed themselves near the castle, awaiting an opportunity for an attack.

A day or two after their arrival several vessels arrived with provisions and arms for the garrison.

As these were being landed Douglas and his followers sallied out and captured the vessels and stores.
