I came across this on the Missouri Partisan Rangers:
Clothing And Weapons Guerrillas - Partisan Rangers
When not wearing Union blue,
Missouri Bushwhackers favored a peculiar piece of clothing called the "
guerrilla shirt," a variation of the coat worn by hunters on the Great Plains. It was a pullover item open, sometimes deeply, down the front.
Four large pockets, two in the breast and two on the sides, were big enough to hold cartridges, preloaded spare revolver cylinders or even small pistols. They came in a variety of colors, and the shawl-coliar front, cuffs and pockets were often decorated with elaborate ribbonwork and needlework by a female relative or sweetheart. The Bushwhackers favored wide-brimmed slouch hats ranging in color from buff to dark brown and black, and often wore their hair shoulder-length. The guerrilla's whole ensemble was meant to create the image of a jaunty, brave, independent cavalier.
Fashion aside, what made the greatest impression was the small arsenal carried by Bushwhackers. Each armed himself with revolvers carried on a gunbelt, in pockets and saddle holsters; some carried as many as six, and their instant firepower against soldiers carrying single-shot,
muzzle-loading rifle-muskets gave them a considerable edge. The favorite pistol was the Colt, especially the lighter .36cal
Colt Navy, which was considered better for firing from horseback. A
Bowie knife or even a tomahawk would be carried for hand-to-hand fighting. The favorite longarm was the
breech-loading .52cal
Sharps rifle, both for its accuracy and its speed in reloading; a trained marksman could fire this rifle up to ten times a minute. It had a maximum range of 800 yards and an effective range of about half that. Because the Sharps was a
breech-loader, it could be reloaded while on horseback or lying down - a clumsy task with a standard muzzle-loader. A carbine version was also produced for cavalry work.
