The acquisition of this pair came at a cost to the British RN.
Funding did not simply come from thin air and would reverberate for a few years, politics dictated reluctantly their incorporation and duly the 4th Minotaur class armoured cruiser Orion and the projected 3rd Lord Nelson class battleship would be sacrificed.
The Lord Nelson issue was one which coincided with the development of the Dreadnought and may consequently be considered irrelevant in view of future developments, but that duo, Lord Nelson and Agamemnon* proved to be an extremely good design in the fullness of time.
Triumph was sunk by U21 off Gaba Tepe during the Dardanelles campaign, Swiftsure became the 1st of the RN's 'pre Dreadnoughts' to pay off on 26 April 1917 when she was duly disarmed and later stripped to act as a blockship in Sept 1918 when the armistice intervened. Scrapped by Stanlee, Dover 1920.
*Agamemnon. This was NOT her original name. King Edward VII had proposed another VERY famous name, but backed down.
Since Trafalgar in 1805 and the British victory over the French / Spanish the RN has almost continuously had a ship named either Nelson, Trafalgar or Agamemnon which was Nelsons favourite ship.
Agamemnon, who was King of the Mycenae, is also the name which carries the battle honour - Trafalgar 1805.
A full broadside. The traditional English salute.
