Who won in the Battle of Shiloh?

Answer 1

This was considered a Union victory, despite the fact that the Union forces - comprised of Grant's Army of the Tennessee and Buell's Army of the Ohio - actually suffered more casualties than their Confederate counterparts. Confederate forces, commanded by Generals Albert Sidney Johnston and P. G. T. Beauregard not only retreated after the Union forces received reinforcements, but failed in their objective of stopping Grant's army from controlling vital railroads and waterways to Southern strongholds, thus opening the door for subsequent Union victories at Memphis and Vicksburg. Moreover, the Confederate troops at Shiloh were poorly equipped and inexperienced in battle, allowing the Union to win smaller skirmish victories while pursuing several disarrayed Confederate battalions retreating after the major bloody battle had finished.

In short, the Union strategically outmaneuvered the Confederacy at Shiloh and, despite the Confederates' advantage of launching a surprise attack, Union forces held their ground (for the most part) and caused Johnston and Beauregard to retreat with troops in much worse shape than their enemy, leaving the South vulnerable to further attacks.
