In concrete terms, and with charts and statistics, this is the record of the Services of Supply, the story of large scale logistics. From D-Day on, this is how the requirements of the invasion operations were met and maintained, complicating factors of shipping and unloading and transportation, ports and railways and maintenance depots: the vital necessities, -- food, ammunition, medicines, reenforcements, etc. and how each was sustained. An overall resume -- of military interest largely. And as a record for the boys who were in this branch of the service -- and their families -- data now released by the war department -- formerly secret.
