Wellington ordered his commanding Royal Engineer, Colonel Sir John Carmichael-Smyth, to prepare a map of the area of Waterloo. It was constructed in 1815 and partly drawn by Major John Sperling RE. When Wellington called for the map it was not quite complete so the original sketches were rushed from Brussels by Lieutenant Marcus Waters. Wellington is said to have marked on the map where he wished his troops to be deployed and passed the map to his Quartermaster General, Sir William de Lancey. De Lancey was wounded on the battlefield whilst carrying the map but Major John Oldfield, Brigadier Major RE, saved the map and wrote its history on it.
