Love After Waterloo by Suzi Love.
Despite Wellington’s victory over Napoleon four days earlier, soldiers, to use the term loosely, still lingered around Waterloo. They and deserters from both sides had joined local famers in picking through the remains of bodies, uniforms, and armory to pilfer anything of value. There’d been nowhere safe to hide her and her son, Daniel, so Lady Melton’s’ brothers had packed what remained of their equipment and taken them, along with a few wounded British soldiers, to the Captain’s quarters, knowing that his orders were to protect whoever remained of French stragglers and deserters. 

Anne’s twin brothers hadn’t lingered, because Wellington and what was left of his British troops were marching back towards Brussels and Brendon’s skills as a physician were urgently needed. Benjamin, an aide to Wellington, had stayed to organize the repatriation of their soldiers and the departure of their sister and nephew. Neither twin had understood her reluctance to join Captain Belling and his group and had ignored her pleas to stay with them in Europe, stating firmly that it was time that she and Daniel returned to London.

They hoped that Anne could reopen their townhouse in London and prepare for when they could join her, optimistically within a few weeks. She wasn’t quite so optimistic. Napoleon was an egotist. He wasn’t the type to accept defeat easily, and she imagined he’d already be making plans for a triumphant return in the future, despite the carnage left behind at Waterloo when he and his remaining troops retreated. Her brothers had reported that the plains had been covered with the dead and the dying, both men and horses.
