Subsequently, the Battalion participated in campaigns in Normandy, Northern France, Rhineland, and Central Europe, and Luxembourg.

After World War II the Battalion was inactivated on 25 October 1945 at Fort Leonard Wood, Missouri. It was reactivated on 17 August 1950 at Ft.

In December 1957 the Battalion was restationed at Anderson Barracks, Dexheim, Germany. Simultaneously with the relocation of the 8th Infantry Division Headquarters to Bad Kreuznach, Germany.

Motto: Id Perficiemus (We shall consummate the task!)

Full history of unit

The Battalion was organized at Ft. Jackson, S.C. on July 1, 1940, under General orders no. 12, Headquarters, Fourth Corps Area. The cadre was picked from the 1st Engineers at Fort DuPont, Del., and from the 7th Engineers at Ft. Custer, MI. The remainder of personnel was received through voluntary enlistments, and the Selective Service.

At that time billets consisted of huts in the National Guard area of Fort Jackson. The first Commanding Officer was Major Patrick H. Tansey. Major Charles H.Mason took over the command in August 1941 and was subsequently followed by Major Edmund M. Fry. This change took place on August 22, 1942, and from December 1942 until February 1943, when Major Fry was sent to Engineer School, the command of the Battalion was administered by Major James C. Taylor. However, Major Fry returned to the outfit to remain the guiding hand through all the Battalion's campaigns.

The usual basic training was given the Battalion while at Ft. Jackson, and it was here that they also received their foretaste of what real combat would be like while they were on Carolina maneuvers in the fall of 1941. However, this proved to be a very minute taste of the real thing, although the combat test at the time was very convincing to a majority of the men.

Completion of the maneuvers found the outfit on the way back to Fort Jackson Where they were given more intensive training, and then used to supply the cadre for two new divisions. In the fall of 1942 the Battalion moved out amidst of many murmurings on the part of the men as to when things would really roll. This move involved large scale maneuvers in Tennessee. The Battalion was lodged at Camp Forest, Tennessee in a tent city, While its strength was brought almost up to normal. The weather at this time was bitterly cold, And right in the middle of one of the worst cold spells, the Battalion moved to Fort Leonard Wood, Missouri. This move was accomplished by truck, And by the time the organization reached their destination, it seemed problematical in the minds of many of the men whether they would ever again resume a semblance of straight posture. The weather remained icy during the whole of their stay at Fort Leonard Wood, and those who returned from the European war claim that even after the fighting on the other side they were last being thawed out from the Paul Bunyan cold.

The next move was a distinct change. The battalion took to the road again and ended up in the lively and bustling Laguna Desert Camp in Arizona. While at this camp-site, Id Perficiemus  — "We Shall Consummate the task"— is the motto that has inspired the 12th Engineer Battalion since it was constituted at Ft. Jackson, South Carolina on July 1, 1940. For the past two decades, the 12th Engineers have proven time and time again that it is capable of performing any task, in war or peace. Today the 12th engineer Battalion with its headquarters in Dexheim, undertakes Engineer construction throughout the 8th Infantry Division. The battalion is heavily equipped with a vast array of construction machinery capable of supporting any engineer task required to support the 8th Infantry Division.

In its role as the division Engineer Battalion the 12th has the mission of providing general engineer support to the various elements of the division. Four Combat Engineer Companies support the three infantry brigades with the construction of barriers, laying and clearing of minefields, demolition operations and limited construction operations. In addition, each of the four companies is equipped with a Combat Engineer vehicle which carries a bulldozer blade and a 165 mm demolition gun capable of destroying enemy barricades,  and fortified positions.

A bridge company provides the Division with its river-crossing capability. Equipped with Mobile Assault Bridge (MAB) units which can be driven on land, and then launched into water to link up with one another (to form a complete bridge, or a series of ferries) the MAB's enable the entire division to cross the Rhein River. The bridge company is also equipped with Armored Vehicle Launched Bridges, which can be used to bridge 60-foot streams.

The 12th Engineers has a platoon of heavy earth moving equipment, including 5-ton dump trucks, rough terrain cranes, and road graders. In addition, an atomic demolition munitions platoon gives the division an added defense capability.

The 12th Engineers are constantly training in their Engineer Support Role, conducting bridge operations on the Rhein, performing earth-moving tasks in community assistance projects, and constantly demonstrating readiness to live up to their motto.
