On 30 Mar 1296 Robert Clifford 1st Baron Clifford (age 21) captured Berwick on Tweed [Map] from William "Hardy" Douglas 2nd Lord Douglas (age 56). Richard Cornwall (age 44) was killed during the course of the siege.'When the town had been taken in this way and its citizens had submitted, Edward spared no one, whatever the age or sex, and for two days streams of blood flowed from the bodies of the slain, for in his tyrannous rage he ordered 7,500 souls of both sexes to be massacred. So that mills could be turned by the flow of their blood.' - Account of the Massacre of Berwick, from Bower's Scotichronicon.
