Probably detached from one of four issues of Whiggeries and waggeries, London : William Strange, 1834. This publication reprinted wood engravings by Robert Seymour, Robert Cruikshank, and others which had previously appeared-- often with different captions-- in Figaro in London, also published by Strange. The identical image appeared in Figaro in London, no. 25, 1832, with the same title.
The 'Army' retreats (right to left) under a shower of cannon-balls; a chain-shot has just decapitated Cumberland. Wellington, stooping low, carries a tattered flag inscribed 'Conservation'; just behind him is Lyndhurst (?) with a broken drum. In ignominious flight (right) is a fat bishop, his mitre inscribed '10th'.
