Some were taller, and standing upright to what appear to be five or six inches, others had much larger crowns which weren't corded around the edges, but flat like the Union picture shown, only more so. There were a number of Union and Confederate kepi styles that did not look like the two shown or the French style, which is much the same. You can pull the cap up, but as soon as you release it falls right back to a somewhat squashed look. On a properly made forage cap, it pretty much falls where it will. You can do this to a poor quality forage cap reproduction (this is because the fabric is too heavy). You really can't squash a kepi down or pull it up. 'Wasn't a 'style' for infantrymen to squash the kepi down and push the top forward, particularly the taller kepis?'
