Who said the following? ' Now is your time Maitland !!.. Now is your time!!!?

Answer 1

You do like your Napoleonic History. As the previous respondent has said it is Wellington at the Battle of Waterloo 18th. June 1815.

Late in the day as the tide turned to the British/Allied army. The 3rd Regiment of Chasseurs approached the ridge opposite Maitland’s Brigade of Foot Guards (2nd and 3rd Battalions of the 1st Foot Guards). Wellington called to the brigade commander “Now Maitland. Now’s your time”. One authority had him as saying “Up Guards, ready”. The Foot Guards stood, fired a volley and charged with the bayonet driving the French Guard back down the hill.
The last of the French Guard regiments, the 4th Chasseurs came up in support as the British Guards withdrew back over the ridge. Sir John Colborne brought the 52nd Foot round to outflank the French column as it passed his brigade, fired a destructive volley into the left flank of the Chasseurs and attacked with the bayonet. The whole of the Guard was driven back down the hill and began a general retreat to the cry of “La Garde recule”.
