and it's interesting to see what happened at gettysburg and again at cold harbor and peetersburg if you look at the bouncing around. and the one i show you next is one of miy favorites. so this is the swings in value. so what it is is essentially the last slide but how things change from period to period. and this one, i think, shows really how the values went up and down around the full-time of m major values. so everything that's above zero means that the currency is depreciating against gold and everything below zero means that the currency itself is appreciating against gold. so if you look at this, i know there's a lot to absorb here. but for the union, not to surprising. things wr pretty bad for their currency after fredericksburg. they were pretty good after gettysburg. and they were pretty good after petersburg. and so monetary markets, i think, really clearly reflect what was going on on the battlefield, as well. in fact, i'm going back to this one here. what happened with confederate currency looks a lot like german currency after world war ii -- i'm sorry, for world war i. hy
