At the heart of most sacks – in terms of motivation, behaviour and the broad participation of common soldiers – lay plunder. This chapter explores British sack plunder in the Napoleonic era from multiple perspectives: the broad campaign and siege contexts in which it occurred; the dynamics and rituals of plunder on the ground; and the attitudes and practices of officers. Most British rank and file participated in the plunder of stormed towns, borne of customary right, the catharsis of passing through the breaches, and opportunism. Despite the seeming chaos, this plunder had its own distinct rituals, conventions and carnivalesque dimensions. Some officers were complicit, too, in tolerating plunder, or indulging themselves; and in India, given the traditions of Company plunder and profit-taking, officers were only too eager to enjoy the official spoils of distributed prize. Yet, whilst there was a general resignation that it was next to impossible to prevent the plunder of stormed towns, most officers, and some men from the ranks, were highly critical of troops doing so, on military and moral grounds, drawing particular attention to the drunkenness, destruction and violence that accompanied it.
