Of the little company of Americans in the French ambulance service,
among whom were a number of former students of the University, were the
two Hall brothers, sons of Dr. Louis P. Hall, '89_d_, Professor of
Dentistry in the University. Richard Nelville Hall, '11-'12, who later
was graduated from Dartmouth, was killed on Christmas morning, 1915,
when his car was struck by a stray shell, the first American to be
killed in the ambulance service. His brother Louis P. Hall, Dartmouth,
'12, Michigan, '14_e_, later became a lieutenant in the French army, and
eventually captain in the American Expeditionary Forces.

It will thus be seen that Michigan's share in the war did not await the
entry of America among the Allies, although it was not until the forces
of the country were definitely enlisted that her real contribution, in
men and services, was made. With the opening of the great training
camps, the alumni, particularly those of more recent years, as well as
the students of the University volunteered literally in thousands, and
Michigan was soon represented by men and officers in every branch of the
service. They were in the first contingent of the expeditionary forces,
the Rainbow Division, and figured prominently in the earliest fighting
about the St. Mihiel salient, at Cantigny, and later with the Marines at
Belleau Wood. Many were of course held in America, to their disgust, to
train the new levies under the draft law, while others were assigned
particular duties for which their special training had fitted them. Thus
we find Michigan represented everywhere in the Medical and Dental Corps,
the early engineering battalions, the rapidly evolving work of the
signal corps, the military intelligence and censorship divisions, gas
warfare and gas defense, publicity, and perhaps above all, the aviation
service, for which the young college man seemed peculiarly fitted. There
were several Michigan men among the first aviation sections in France;
several were killed and others captured in early combats. The arrival of
the later contingents brought Michigan men with every division; they
were everywhere in the Argonne battle, they were with the famous "lost
battalion," and with the American forces included in the British
sectors, as well as among the engineers who helped to stop the gap after
the disaster to the Fifth British Army.

Perhaps the most striking contribution Michigan made towards winning the
