Love After Waterloo by Suzi Love.

Tired past the point of arguing, Gabe undid the buttons on his trousers and awkwardly sank to the floor. Thin though the mattress was, he groaned with relief to be seated and able to stretch out his aching leg. He bent and tugged at his boots, but Lady Melton swatted his hands away.  “Lean back and let me take care of you.”

He blinked at her in surprise. His uncle’s housekeeper had filled the role of mother for him often enough, but other than Mrs. Green, no one had ever fussed over his physical well-being.  The women he’d been intimate with had fretted over pleasing him sexually, but his role as the male and provider had been to ensure they were well-housed, fed, and clothed. Role reversal made him uncomfortable, and yet Anne’s caring was oddly reassuring. 

His upcoming task wasn’t going to be easy. Eleven men, a lady, and a small boy had to be transported to England. Plus, Wellesley’s dispatches were sewn into the lining of his uniform, which not even the Lieutenant knew. Gabe carried the official summation of the battle, papers that he’d been ordered to personally deliver to the War Office in London. Messengers were adequate for shorter notes, but the War Office needed a full report from Wellington, plus observations from his trusted officers, which amounted to a hefty and valuable package for him to conceal. 

If Anne could lessen his pain, even a little, his thinking would be clearer during their journey, and only an ungrateful idiot would refuse her offer.
