Pulley, Natasha. The Kingdoms
Divergence: 1798 CE
What if: Naval technology from the 1890s, as well as knowledge about history of the early 19th century, was obtained by the French in the late 1790s. Thus the British fleet was obliterated at Cadiz in 1805, and England was invaded in 1808.
Summary: The story of a man with a faltering memory who is displaced out of time, traveling from the 1890s to the 1810s, whence he joins a renegade English ship's crew, and then returns back again. But was it the first time he did so?
