On 30 January 1915 the Avoca Free Press published a letter from Reg to his parents dated 13 December 1914. In his letter Johnson mentions:
- Watty, probably his brother Walter Henry Clarence Johnson (1888-1953), who enlisted at the same time and was also serving with the 8th Battalion
- Dave, probably Dave Summers (1893-1916), who had played with Johnson in the Avoca Brass Band.
- Billy French's accident to his knee; French was repatriated early in 1915 because of it.
- camping near Cairo only about half a mile from the great pyramids pyramids at Giza. Johnson mentions the Sphinx, an Indian wounded by Arabs, two New Zealanders being stabbed, and two men who died falling from the pyramids.
