Gettysburg

Last week, we talked about the Civil war. To go more in depth, the Battle of Gettysburg and the Battle of Cold harbor. Today I will write about the battle of Gettysburg. We talked about how Gettysburg was probably one of the most decisive battles in the Civil War. I was wondering, why they would continue the war for months after? Wouldn't it only deplete supplies until the South would be left with nothing? The most decisive battles took place on little and big round top, and Culp's, and Cemetery Hill. The battle between little and big round top, took place in the area between, the Devil's Dens, also the valley of death. This battle, protected the Union army, from being destroyed by the sides. The leader of the Union army part, was Colonel Joshua Chamberlain. Wouldn't he get more recognition than that which was given? It seemed like his part in the battle was a bit underestimated. The battle on Culp's Hill took place on the last day. The tactics were important, to make sure that the Union Army won. I was wondering, why would General Lee keep trying to send troops through an open field even when his forces were depleted? Wouldn't it be better to recognize the failure and change the strategy to match the situation?
