Confederate loss of the battle of Five Forks was partially blamed on General George Pickett being away on a shad bake:
"When George Pickett accepted Rosser’s invitation to what would become a terribly infamous shad bake, it was regional rite of spring for tidewater Virginians. It was just after the shad run has been made and so the local tradition was in process. Pickett, probably desperate for a hot meal and a little relaxation after many stressful months, eagerly accepted the invitation. For this, it’s hard to retroactively blame the man, even with the union so close. He was an experienced commander and should have known what was coming. However, that he failed to tell anyone in his camp where he would be is slightly hard not to judge. He did not tell his second in command nor any other soldier that he’d be in Rosser’s camp, which has been hypothesized as trying not to deplete the shad.
While Pickett was enjoying his shad and probably a few beverages, Warren attacked. The full assault occurred without Pickett and, since he had failed to tell anyone where he was going, nobody could find him. Also, between Rosser’s camp and Five Forks there was a thick forest that dampened the sound. So nobody in Rosser’s camp knew what was happening. By the time they (he and Pickett) were alerted, there was nothing they could do. By the time Pickett got to his men, nearly a half of them were wounded, dead, or captured. In concert with the Third Battle of Petersburg the following day, Lee was forced to abandon Petersburg, which led to the capture of Richmond and surrender of his army on April 9 at Appomattox."
