Stamm.Kp.Gren.Ers.Btl.65 EKM (Venlo)

The dog tag or 'Erkennungsmarke' shows signs of wear. The Infanterie Ersatz Bataillon 65 was formed in the summer of 1939 and in November 1942 renamed in Grenadier Ersatz Bataillon 65. It supplied soldiers for Infanterie Regiment 65.
In September 1944 the whole bataillon was mobilized and moved to Holland where it became the I.Bataillon Grenadier Regiment 1222 which was part of 180.Infanterie-Division. In 1944 and 1945 it fought in the Venlo area. 
In late September and new Grenadier Ersatz Bataillon 65 was formed in Delmenhorst,Germany.In March 1945 parts of the bataillon where put in to action in the area of Nordwohlde and Syke.
A Stammkompanie was a unit that trained the soldiers. Often the soldier of this kompanie were soldiers who had frontline experience, but no longer were fully usable at the front due to injuries. Of course this changed later in the war as there was a shortage of (front)soldiers and where mobilized also.
The 'B' on both parts of the tag stands for the soldier's bloodtype.
