On Sunday 18 June 1815 the British and Prussian armies, commanded respectively by the Duke of Wellington and Field Marshal von Blücher, won the Battle of Waterloo. There were immediate demands for monuments across Britain to celebrate this great victory, but none were so quick to respond as William Kerr, the 6th Marquis of Lothian, and his family. By the end of June funds had been raised to erect ‘a monument on the summit of Penielheugh’, a lofty hill on the Marquis’s Monteviot estate.
The hero of this tale began life in 1787 as Thomas Monteath. By the time he died in 1868 he had taken the name Douglas as a condition of an inheritance, advanced in the military ranks, and been knighted, thus ending his life as General Sir Thomas Monteath Douglas. He had plans to ensure that he would not quickly be forgotten, and had this extraordinary mausoleum constructed.
