Resources and Links

There are relatively few sources of information about the 145th ECB. The two most important are the unit history compiled by Robert Greenwalt, who served as commander of Company C during much of the Battalion’s time in Europe, and the booklet of photographs taken by Benedetto Ballone, the unit photographer. These are the two primary sources of information, which for the basis for the two formal studies related to the Battalion’s history prepared by officers at the Army Command and General Staff School. The copies I have of the Greenwalt and Ballone documents are both reproductions and are difficult to interpret in places, but provide a tremendous amount of information.

The two Master’s Theses extend the information in Greenwalt’s history. “First on the Line,” by Major Shawn Umbrell, is relevant to the period before the 145th was formed from the 2nd Battalion of the 35th Engineer Regiment, during construction of the Alaska Highway in 1942. “Unit Heritage: Lost and Found” is a very nice resource by Major David Snodgrass. Major Snodgrass undertook this study as a consequence of his assignment to “stand up” the 70th Engineer Battalion in 1992, and began looking into the heritage of the unit to provide the Battalion with a sense of the unit’s history and accomplishment. The 145th ECB was the “ancestor” unit of the 70th, leading Major Snodgrass to dig into the unit’s history. For anyone interested in the 145th ECB, it’s a worthy read.

There are a few items on this site that have not been published before to my knowledge. I received a scrapbook kept by my grandfather, John McGaughey, who was commanding officer of the 145th from at least the Battalion’s arrival in England until early February 1945, when he became ill and had to leave the unit. His scrapbook contained numerous photos and drawings. Nearly all of the photos were from those taken by Corporal Benedetto, but the drawings were different, and showed more of the personality of the Battalion.

I’ve also added a few links to other sites that discuss combat engineers in World War II Europe, both of which are much more thorough. The 300th Combat Engineer site in particular provides a wealth of information about combat engineers and their training.
