A subaltern's memoir of service with the Connaught Rangers during the Peninsular campaigns, offering vivid, often graphic accounts of major engagements — Busaco, Fuentes d’Onoro, El Bodon, the sieges and storms of Ciudad Rodrigo and Badajoz, Salamanca, and the retreat from Burgos — alongside descriptions of daily regimental life, shortages, wounds, and practical improvisations. The narrative mixes detailed battle description and dark humour, recording colourful comrades, surgeons, and servants, and reflecting on leadership, discipline, and the psychology of stormers. Occasional digressions into wider campaign matters appear, but the core remains immediate frontline observation and anecdotal portraiture of an Irish infantry battalion.
