Sorry for horning into your talk page, but I'm still drafting the remount service article and hope to do one on the remount concept as well. Early on the Army decided that it was cost-prohibitive to maintain whole herds, so they used the remount stations to house selected stallions and then contracted out with local horse breeders to provide mares. Robinson was the main headquarters once the Remount Service really got organized (after World War I), but as Montanabw pointed out the majority of the actual stations were in the West. One thing the remount service is credited with (as it was only in operation on a large scale for about 20-25 years) was an overall improvement of the quality of horses in civilian service. This was because the Army didn't (and couldn't) buy all the animals produced by the program and the breeders were allowed to keep those that didn't meet standards or were otherwise unneeded.
