On 26 March 1945, at 0200 hours, the 89th Infantry Division began crossing the Rhine on its march eastward. Imagine the coordination between the divisions, brigades, battalions, batteries to make this happen. As the crossing began, the 914th Field Artillery Battalion provided support to the 355th Infantry Regiment. The crossings were made near St. Goar and Oberwesel. My great uncle Irwin Carl, a corporal in the 914th Field Artillery Battalion, was there. He was one of 88 men in Battery C, positioned 1500 yards east of Niederburg. 
How do I have such detail, down to his exact position? After Action Reports.
After Action Reports typically comprise a narrative, plus S-3 and S-2 Reports and a Unit Journal. The “S” stands for “Staff.” The “3” refers to “Operations,” and the “2” to “Intelligence.” The After Action report is a high-level narrative, written in the weeks after events. It does not give names. For the 914th Field Artillery Battalion, the 10 – 31 March 1945 report was submitted on 1 April 1945.
Reading through the After Action report for 24 – 29 March provides much detail on the Battalion, and each Battery within the Battalion. It details the locations, and exact timing of movements of troops – even the type and amount of ammunition expended.
From reading the primary source material, I know that the Rhine crossing took days – the 914th Field Artillery Battalion, Battery C started crossing at 0130 hours on 28 March 1945 – 48 hours after the first troops headed across – and they finished at 0400 hours on 28 March 1945.
Primary source materials, and drilling down into the details, tells the soldiers’ stories. These documents helped inform this blog post:
