From 1917 British soliders who were unfit or too old for front line service were to serve unarmed and within the range of German guns for weeks or even months at a time undertaking labouring tasks. The vital, yet largely unreported role played by these brave soldiers was crucial to achieving victory in 1918. For this book John Starling and Ivor Lee have brought together extensive research from both primary and secondary sources. it traces how Military Labour developed from non-existent in 1914, to a Corps in November 1918 some 350,000 strong, supported by Dominion and foreign labour of more than a million men. This work provides vital information for those wishing to acquire information about an ancestor in the Corps.
