The regiment trained for several weeks in San Antonio, Texas, and in his autobiography, Roosevelt wrote that his prior experience with the New York National Guard had been invaluable, in that it enabled him to immediately begin teaching his men basic soldiering skills.[104] The Rough Riders used some standard issue gear and some of their own design, purchased with gift money. Diversity characterized the regiment, which included Ivy Leaguers, professional and amateur athletes, upscale gentlemen, cowboys, frontiersmen, Native Americans, hunters, miners, prospectors, former soldiers, tradesmen, and sheriffs. The Rough Riders were part of the cavalry division commanded by former Confederate general Joseph Wheeler, which itself was one of three divisions in the V Corps under Lieutenant General William Rufus Shafter. Roosevelt and his men landed in Daiquirí, Cuba, on June 23, 1898, and marched to Siboney. Wheeler sent parts of the 1st and 10th Regular Cavalry on the lower road northwest and sent the "Rough Riders" on the parallel road running along a ridge up from the beach.
