Seemingly safe in northern New England, the residents of St. Albans, Vermont, were astonished in October 1864 when a group of Confederate soldiers appeared in their midst, terrorizing residents, robbing banks, and stealing horses. In this week's episode of the Futility Closet podcast we'll tell the story of the St. Albans raid, the northernmost land action of the Civil War. We'll also learn about Charles Darwin's misadventures at the equator and puzzle over a groundskeeper's strange method of tending grass.
