I'm not sure that the telegram is connected as the reference is FR, not R, but I'm very happy to stand corrected on that.
The card says he was repatriated 17 Feb 1915, and other records say he was discharged 2 Oct 1915 due to wounds.
I don't know exactly when he was captured but he first landed in a theatre of war 4 Oct 1914, so he wasn't on active service for long.
