This is the section citation for SSU 641. When Harry Crosby's American Field Service section, SSU 71, was taken over by the US Army Ambulance Service they became SSU 641 after taking over the Fords of SSU 29. Some members of 71 left to join other military units and some were sent to fill vacancies in other ambulance sections but a large number of men remained including the AFS section chef, now lst Lt.,
Roland R. Speers.
The citation, for the entire unit, was earned for the period of August 23rd,24th, and 25th 1918 for evacuation of wounded under heavy German bombardment. Harry Crosby was on leave in Paris during this time with one of his friends from the section--Lawrence Honig. Each member of 641 received this document.
