Welsh Horse

The Welsh Horse unlike the other Yeomanry regiments was newly formed and raised in 1914, almost single handed by their aspiring Commanding Officer Lt Colonel Arthur Owen Vaughan DSO OBE DCM. During the Great War the Regiment would raise three regiment but only the First Line Regiment would see active service - as Infantry. In the event, Vaughan was not given command; this went to Lord Kensington, a well-known Pembrokeshire landowner, instead.
