Iron Age Logistics
As the size of armies and the scope of battles increased, ancient armies had to master the task of logistically supporting these armies in the field. The logistical feats of ancient armies were often more difficult and often achieved more proficiently than in armies of the nineteenth century [C.E.], when the railroad, mass production of weapons, standard packaging, and tinned and condensed food made the problem of supply considerably easier. The need to support armies in the field for months, sometimes years, was a function of the rise of the imperium. Armies now had to conduct combat operations over far wider areas for longer periods than ever before.
Changes in the composition of military forces also added to the logistics burden. The development of the chariot required that the Egyptian forces maintain repair depots and special mobile repair battalions to ensure that the machines remained functional on the march. The Assyrian invention of large cavalry squadrons brought into existence a special branch of the logistics train to ensure that the army could secure, breed, train, and deploy large numbers of horses to support these new forces. This special logistics branch, the musarkisus, was able to obtain and process 3,000 horses a month for the Assyrian army. It was not until the time of Napoleon that Western armies could once again equal this logistical feat. The integration of chariots with cavalry also forced the Assyrian army to become the first to learn how to sustain 2 types of transport. Advances in siegecraft required that armies transport siege towers and engines within their baggage train, and artillery, introduced under the Greeks and brought to perfection under the Romans, added yet another requirement to transport catapults and shot. The need to manufacture, issue, and repair the new iron weapons in unprecedented numbers required yet more innovations in logistics. In the Assyrian army the production and storage of weapons became a central feature of the army’s logistical structure. A single weapons room in Sargon’s palace at Dur-Sharrukin contained 200 tons of iron weapons, and similar weapons warehouses were scattered throughout the empire. Of all the achievements of the ancient armies, those in the area of logistics often remain the most unappreciated by modern military planners.
