1870. This edition contains both Volumes I and II of this work. Mercer was commander of the G Troop, Royal Horse Artillery, in Wellington's army and achieved fame as the Captain who disobeyed Wellingtons orders to abandon the guns and take shelter with the infantry when the French cavalry closed in. He was in the habit of jotting down notes on the events of the day each evening. This is the account of what he saw and felt from leaving Colchester for Belgium 1815 to his final return to England in 1816. It is a remarkable and compelling account, especially of the three days which ended the career of Napoleon. Mercer's troop was at Quatre Bras, where he got off a few rounds at Napoleon himself, and at Waterloo. There are graphic descriptions of the battles and of his tour over the battlefield the day after, with its appalling scenes of carnage and the sight of the locals looting the dead, and the not-quite dead. It is an outstanding example of the literature of the Napoleonic wars, and it has a rarity as the memoir of an artillery officer, and a troop commander at that.
