IV With the Guns at Waterloo
Mercer, the author of the “Journal of the Waterloo Campaign,” came of a soldierly stock. His father belonged to the Royal Engineers, served on the staff of Sir Henry Clinton in the American War of Independence, and rose to the rank of general. Cavalie Mercer, with whose book we are concerned, was born in 1783, passed through the Military Academy at Woolwich, obtained a commission in the artillery at sixteen, and had not reached the retired list when he died at the age of eighty-five. But though his career as a soldier was long and honourable, it cannot—except for the three great days of Quatre Bras and Waterloo—be called very inspiring.
Mercer’s first military service was in Ireland at the time of the rebellion. War is always hateful, but its blackest form is civil war. Mercer was next unfortunate enough to take part in the most ignoble expedition known to British arms—Whitelocke’s shameful and unhappy performance at Buenos Ayres. This was the worst school imaginable for a young soldier, but Mercer had fine military gifts, and though he was shut out from the Peninsular campaigns, when he made his appearance on the field of Waterloo he showed himself to be an artillery officer of very fine quality—cool, skilful, and gallant. He served after the peace in North America, and commanded the artillery in Nova Scotia in the troubled days of the Maine boundary-line dispute, when it seemed likely that England and the United States would drift into war.
Mercer’s long military career found its climax in the three memorable days of June 16-18, 1815; and the splendours and terrors, the bloodshed and the triumph of those mighty battles are vividly reflected in his pages.
