How did steamships improve the movement of troops and supplies?

During the 19th century, the introduction of steam propulsion and advancements in ship construction significantly enhanced military logistics by providing new capabilities for the movement of troops and supplies.1

Unlike sailing vessels, which were dependent on wind conditions, steamships offered more reliable and predictable transport. This technology was utilized to support military operations in several major conflicts, including the Mexican-American War and the Crimean War, where they were instrumental in moving armies. Additionally, river steamboats played an indispensable role in logistics during the American Civil War.1

These improvements were supported by concurrent engineering milestones, such as the development of more efficient compound-expansion steam engines and condensers that allowed for the use of fresh water in boilers, which increased the operational range and reliability of naval vessels. Together, these innovations allowed military forces to project power more effectively across both coastal and inland waterways.21
