The Armistice of Mudros was signed aboard Agamemnon, not Lord Nelson. Agamemnon then took part in the occupation of Constantinople while Lord Nelson entered the Black Sea. Both ships returned home and went into reserve by mid-1919, but Agamemnon received one more technical role as a radio-controlled target ship. Dreadnought-era battleships fired on her to improve their gunnery before she was sold for scrap in 1927, seven years after Lord Nelson's sale.
