I am building an ox wagon of the general type used by the Brits in the Anglo-Zulu War and I'm having trouble finding the method used for hitching. All of the models that I've seen show a pole type hitch but I think that is incorrect. It is stuck in my mind that the Boers used a chain fastened to the back underside of the wagon then brought forward, fasten to front underside then hitched to each yoke. I'm sure that I read that somewhere but can't find the reference. That type of hitch, if I recall correctly, made it possible to turn the 12 - 16 ox teams much more tightly. I've looked at lot of images of oxen in-spanned but none show the attachment clearly. Can anyone shed light on the method or refer me to a good reference?
