Freed from English threats, Scotland's armies could now invade northern England. Bruce also drove back a subsequent English expedition north of the border and launched raids into Yorkshire and Lancashire. Buoyed by his military successes, Robert also sent his brother Edward to invade Ireland in 1315, in an attempt to assist the Irish lords repel English incursions of in their kingdoms and to regain all the lands they had lost to the Crown (having received a reply to offers of assistance from Domhnall Ó Néill, king of Tír Eoghain), and to open a second front in the continuing wars with England. Edward was even crowned as High King of Ireland in 1316. Robert later went there with another army to assist his brother.
