First was a Harry Turtledove novel in is Crosstime Traffic series, called In High Places. A young woman working in a CT trading post is captured by slavers, and sold to another group who take her crosstime to another culture, and use her as slave labor. How she copes is the point of the novel. It's not a bad read, but others that I've read of this particular series were better.
The other book was Osprey Men-at-Arms #42: The King's German Legion, about the history of a unit of Germans who hale from an area where the British King has some political clout. They fought in the Napoleonic Wars and disbanded well after Germany became a nation. This was an older version of Osprey, and the quality of the plates wasn't as good as the series later became.
