JOURNAL. OF THE WATERLOO CAMPAIGN. By the late General Cavalie

Mercer. With an introduction by the Hon. Sir John Fortescue. (Peter Davies. 10s. 6d.)--A reprint of Mercer's admirably graphic narrative of the Waterloo campaign is distinctly welcome. It was not published till 1870, and few but military students know it. Captain Mercer commanded G Troop, Royal Horse Artillery, and did good service in the battle, though he had been too late in arriving to assist in the delaying action at Quatre Bras two days earlier. His account of Waterloo is most vivid because he only describes what he saw. His battery suffered most when later in the day it was shelled by a Prussian battery, which had come up on its left flank and mistook the English guns for the enemy's. Mercer turned his guns on the Prussians and soon had a Black Brunswicker remonstrating furiously with him. Mercer describes the Allied occupation of Paris in considerable detail iu the later chapters of his most interesting book.
