The second major plot consists of the fortunes of Tristram's Uncle Toby. Most of the details of this story are concentrated in the final third of the novel, although they are alluded to and developed in piecemeal fashion from the very beginning. Toby receives a wound to the groin while in the army, and it takes him four years to recover. When he is able to move around again, he retires to the country with the idea of constructing a scaled replica of the scene of the battle in which he was injured. He becomes obsessed with re-enacting those battles, as well as with the whole history and theory of fortification and defense. The Peace of Utrecht slows him down in these "hobby-horsical" activities, however, and it is during this lull that he falls under the spell of Widow Wadman. The novel ends with the long-promised account of their unfortunate affair.
