This book uniquely encapsulates the experience of Canadian militia gunners and their units into a single compelling narrative that centres on the artillery units of New Brunswick. The story of those units is a profoundly Canadian story: one of dedication and sacrifice in service of great guns and of Canada. The 3rd Field Regiment (The Loyal Company), Royal Canadian Artillery, is Canadas oldest artillery unit, dating to the founding of the Loyal Company in Saint John in 1793. Since its centennial in 1893, 3rd Field -- in various permutations of medium, coastal, and anti-aircraft artillery -- has formed the core of New Brunswicks militia artillery, and it has endured into the twenty-first century as the last remaining artillery unit in the province. This book is the first modern assessment of the development of Canadian heavy artillery in the Great War, the first look at the development of artillery in general in both world wars, and the first exploration of the development and operational deployment of anti-tank artillery in the Second World War. It also tells a universal story of survival as it chronicles the fortunes of New Brunswick militia units through the darkest days of the Cold War, when conventional armed forces were entirely out of favour. In 1950 New Brunswick had four and a half regiments of artillery; by 1970 it had one -- 3rd Field. The book traces the rise and fall of artillery batteries in New Brunswick as the nature of modern war evolved. From the Great War to Afghanistan it provides the most comprehensive account to date of Canadas gunners.
