Is it possible Lee's most decisive victory set the stage for his defeat at Gettysburg? Let's talk about it. At Chancellorsville both armies suffered loses. The losses suffered by the ANV were costly to say the least. Losses in command that handicapped Lee's forces. I'm not just talking about Jackson. He lost a large percentage of commanders on all levels. Attrition began taking it's toll. The loses suffered by the AOP afforded opportunities to officers who were not previously in a position to make a major contribution at Gettysburg. These officers proved not only to be confident but also aggressive. Could Robert E. Lee's most decisive victory have set the stage for his most devastating defeat?
