Plumer Street was named after Field Marshal Plumer who was another who Haig did not get along with.
He was regarded as a meticulous planner and was made Commander of the British 2nd Army.
He was responsible for the assault on Messines Ridge in 1917, where they tunnelled under the ridge and blew it up. He told the officers the night before that ‘Gentleman, we may not make history tomorrow, but we shall certainly change the geography”.
This was the loudest noise ever made by man – Lloyd George is said to have heard it at Downing Street.
