Congressman Lincoln and the return of the wooden leg of General Santa Anna

[L Verge]

I know next to nothing about the Mexican War and even less about Mexican history. I do know that I keep seeing the town of Matamoras mentioned a lot during the Civil War - and am interested in it because Isaac Surratt's unit went into Matamoras near the end of the war.

Someone please edumacate me on this. Also, wasn't Mrs. Quesenberry's sister somehow involved in the politics of the Maximilian during our Civil War?
