". . . Buford served in Utah under Gen. Albert S. Johnston, during President Buchanan’s ill-advised campaign against the Mormons. While stationed at Fort Crittenden, Buford studied cavalry theory and tactics, adopting the then-radical concept that cavalry could be better served by fighting as mounted infantry. This approach to combat would serve him well six years in the future, when his small force confronted the Army of Northern Virginia outside the small town of Gettysburg, Pa. . . . "
". . . Using his two unsupported cavalry brigades as mounted infantry, Buford dismounted his men and stationed them along a ridge just a few miles from town, in the path of the oncoming rebels. One man in four stood to the rear holding the horses for the others. This effectively left him with only 2,200 men – stationed at wide intervals – to hold the high ground. The line was anything but formal, with Buford’s men taking cover as best they could, aiming their breech-loading Spencer carbines from behind trees, bushes and fence posts. Buford strategically placed his six cannon for maximum effect. Lt. John Calef, commanding the guns, aimed one cannon at a group of rebel officers nearly a mile distant, and fired. As Bruce Catton understates it, “The flash and the echoing report and the bursting shell notified the Confederates that they were expected.”. . . "
