What the men could write about was everything else: the weather, the food, the people they were meeting, the landscapes they were moving through. These were the letters that reached home, carefully drained of the specific content that made the service distinctive. The families who received them had no way of knowing that the writer was part of the first mobile multimedia tactical deception unit in U.S. history, that he was spending his days positioning fake tanks in German fields, that his unit might be responsible for saving thousands of American lives.
The sketchbooks filled a part of this communication gap. Visual records of places and people, with no operational information, could be kept without raising censorship concerns. Some men sent drawings and sketches home. These personal records, made by trained artists who were soldiers, became over time one of the most remarkable documentary legacies of an unusual military experience.
## The Specific Geography of Viersen
The area around Viersen in western Germany — the Rhineland industrial zone near the Dutch border — was the specific terrain in which the 23rd’s final and most consequential operation played out.
The Rhine River in this sector runs generally north-south, with the German industrial heartland of the Ruhr to the east and the Netherlands to the west and north. In early 1945, as the Allied armies pushed toward the river, the terrain was a mix of industrial town, agricultural flatland, and the river itself with its network of tributaries and canals. The area had been contested territory during the German advance of 1940 and had seen fighting again during the Allied approach.
