Narrative of the March of Co. A, Engineers from Fort Leavenworth, Kansas, to Fort Bridger, Utah, and Return, May 6 to October 3, 1858

The narrative presents a first-person account of a mid-19th-century army engineer company's long overland march across the Plains to the mountain West and back, focusing on day-by-day details of route-finding, construction of crossings and roads, logistical challenges, weather, camp life, interactions with other units and supply trains, incidents such as illness and a comrade's death, and the practical work of maintaining a marching column. Entries blend travel diary immediacy with technical descriptions of engineering tasks, revealing the grueling pace, resourcefulness, and routine labor required to move a military force through sparsely settled territory.
