This image comes from a postcard dating from May 1916 and shows the Royal Army Medical Corps taking a rest by the Clock Tower in Market Square after a march.
One of the men in the group was Russell Steward from Norwich who wrote to his wife Rosa, thanking her for the letter she sent him.
The Royal Army Medical Corps was formed on June 23, 1898. Soon after they were formed they saw action during the Boer War (1899-1902).
They treated 22,000 wounded and 74,000 for dysentry and typhoid fever.
At the outbreak of the First World War the RAMC consisted of just 9,000 and by the end of the war the corps had 154,000 in the ranks.
This clearly illustrates the great need for more people during that bloody conflict.
It is likely that many of the men pictured here never came home again.
However, Russell Steward did survive and returned to his wife in Norwich, although they only spent a few short years together before she died in 1924.
