The English King Edward replaced the castle with a much sturdier structure at the south end of Castle Loch around 1300 and its remains still show the massive strength of its defences. Archibald Douglas, Lord of Galloway, with the assistance of the Earls of March and Douglas, after a siege of nine days, took Lochmaben Castle from the English and "razed it to the ground" on 4 February 1384/5. The castle and barony became a possession of the Earls of March, but when the 10th Earl was forfeited and then reinstated, in 1409, it is noted that it was "with the exception of the castle of Lochmaben and the Lordship of Annandale."
