You are the first person with a family connection to the 210th that I've been able to connect with. Very happy that you posted. I have been collecting information on the Company for a while with the goal of assembling a simple book to follow my grandfather's time in the 210th. I'll assembly a summary and forward you a collection of documents in a couple of days.
I am the grandson of a WWII and D-Day Army veteran. He was in the 210th Military Police Company, a unit which was attached to, and trained with the 5th Engineer Special Brigade (5th ESB) at the start of the war. The Brigade itself was formed specifically to support the landing of the U.S. 1st and 29th Infantry Divisions on Omaha beach by way of clearing beach obstacles; marking and clearing mines; establishing roads off the Beach; and supporting the movement of men and material off the landing crafts/ships and into various depots in and around the landing areas. The core of the 5th ESB was made up of the 37th, 336th and 348th Engineer Combat Battalions with one Platoon each of my grandfather's 210th MP Co assigned to each of these three Engineer Combat Battalions for the D-Day landing. After landing in France, my grandfather's MP company worked traffic control for the Red Ball Express, and moving with it through France, Belgium, and into Germany. Hello to all!
