This photograph of Captain William Davies at Stanford University, California, surrounded by the Messrs P. L. Roberts junior and senior, was taken in July 1916.

This document was brought to the attention of the U-Boat Project 1914-18 by William Davies's grandsons, John Davies, Denbigh, and David Davies, Mold, who inherited their grandfathers' documents and naval artefacts and kindly allowed us to share it.
