Martha, If you're referring to the label of the map that says "292 Engineer ("C") Battalion," that's the official designation, 292nd Engineer Combat Battalion. It doesn't stand for Company C in that case. As far as I know, all the companies were involved in the same campaigns and battles, although they did have differing duties during, for example, the Roer River crossings. They were all there, rotating duties.
Hope this helps,

Hi Martha,
Pete is correct, the map represents the movements of all the companies of the 292nd. As Pete has stated the companies at times were working on separate tasks but the battalion as a whole were apart of the same campaigns and battles. You can use the 292nd timeline I previously posted for you to see the dates for the movements shown in the map. We have been funneling a great many documents gathered from the National Archives and other sources to Gary who is going to digitize them for everyone to easily reference. Once this project is complete you will be able to read in much detail about the daily activities of Company A as well as the rest of the 292nd companies. Stick around and I guarantee you will learn a lot.
