First World War period Despatch Riders photographs

A couple of nice early pictures of military machinery.

The solo up front is a Triumph and I believe the sidecar
machines are all Royal Enfields with Vickers v-twin motors.
Picture taken in Surrey.

Unmistakably a Triumph.  I believe the picture is taken in
France and to look at the rider this seems to be so. I would have
said an earlier bike than the 'Trusty Triumph' Model H that saw
so much use in the First World War. Perhaps then an earlier civilian
bike pressed in to service or the photo is simply pre-1914.
