Herbert Maxwell,
Robert the Bruce and the struggle for Scottish independence
(1909)
“ His deep love for the Bruce was fully returned, and King Robert gave passing expression to it in a charter of lands granted to the bishopric during Wishart's captivity, dated April 26, 1309. "We feel in the depth of our heart the imprisonment and chains, the persecution and duress, which the venerable father, Lord Robert, by the grace of God Bishop of Glasgow, has hitherto endured and still patiently endures, for the rights of the Church and our kingdom of Scotland." ”
