Few historical figures are as inextricably linked as Ulysses S. Grant and Robert E. Lee. But less than two decades before they faced each other as enemies atAppomattox, they had been brothers--bothWest Pointgraduates, both wearing blue, and both fighting in the same cadre in the Mexican War. They were not alone: Sherman, Davis,Jackson-nearly all of the Civil War's greatest soldiers had been forged in the heat of Vera Cruz andMonterrey. The Mexican War has faded from our national memory, but it was a struggle of enormous significance: the first U.S.war waged on foreign soil; and it nearly doubled our nation. At this fascinating juncture of American history, a group of young men came together to fight as friends, only years later to fight as enemies. This is their story. Full of dramatic battles, daring rescues, secret missions, soaring triumphs and tragic losses, THE TRAINING GROUND is history at its finest.
