beaurega beauregard, the battle of shiloh, is reputed to have created this confederate formation by putting one of his corps in the front line. i should -- you probably no albert sydney johnson commanded the army at shiloh. beauregard in second command. beauregard devised the battle order and drew up the formation. he put one corps in line there. one corps in line directly behind it and the other two corps filed in in what is known as column of brigade. the definition of column vary depending on what level of command we're talking about. and the military sense, a column is a series of formations stacked one behind the other, whether they are packed tight or spread out, what was considered a deployable difference so they could move more flexibly. so a column of brigade, for instance, would mean infantry in line. all the regiments in line and each brigade in that division would be stacked one behind the other just like this depth of column. the interesting thing to me about these two formations sort of, and this one admittedly is harder to see, but stonewall jackson did something very similar
