Focussing on a reading of the ‘Thanksgiving Ode’, and its accompanying shorter poems, this chapter sets Wordsworth’s post-Waterloo compositions within the context of broader, contemporary debates concerning the relations between war, religion, and sacrifice. While elsewhere in the Thanksgiving volume attempts are made to cleanse the ‘stains’ of a ‘perturbèd earth’, the ‘Thanksgiving Ode’ remains dogged in its attention to the human costs of ‘victory sublime’, an attention that, this chapter argues, should be read within the larger context of Wordsworth’s struggle to submit Imagination to the will of God. With memories too of how, in 1802, peace conflated the distinctions between union and disunion, legitimacy and illegitimacy in Wordsworth’s sexual relations, the ‘Thanksgiving Ode’ tacitly acknowledges the recent wedding of the poet’s daughter, Caroline Wordsworth-Vallon. Figured as the bearer of conflict and as a principle of restitution, Caroline hovers on the margins of the ode, a symbol of peace founded in war.
