At the outbreak of the Second World War Morecambe became an important RAF station and the Midland was requisitioned by the Government for use as a military hospital.
Valuable items were put into store and the interior of the building converted. On the ground floor the dining room became a large ward with some forty beds, while the circular café was adapted to serve as a physiotherapy centre. Other rooms were used for administrative purposes.
Although there was a mortuary in the basement of the building, very few people actually died in the Midland, the more serious cases being transferred to Lancaster Infirmary.
