Marvin Davis, Sr.
was one of the first men to arrive at Los Alamos in April 1943 as part of
the initial contingent of military police. This first group was the
1st Military Police Detachment - Mounted and originated at Fort Riley,
Kansas. The first contingent of 100 or so men traveled through Camp
Wolters, Texas on their way to Los Alamos. Mr. Davis was also a
member of the first 12-man group that traveled to the Trinity Test Site to
establish a secure test zone. Mr. Davis has graciously submitted the
below referenced photos and documents to help students and researchers
better understand the origination of the military police at Los Alamos
