4 base hospitals

•  Located near the coast so wounded men could be shipped back to Britain
•  As the war went on, CCSs did more of the jobs originally intended for Base Hospitals
•  Divided patients up into different wards according to their wounds. This allowed doctors to experiment and specialise in particular injuries
•  In 1918, the Germans launched a last-ditch offensive which threatened the CCSs, so much of the surgery was once again carried out in the Base Hospitals.
