Bret Devereaux devotes a long blog post to pre-railway army logistics. It was complicated and subject to the "tyranny of the wagon equation", at least on land: whatever carries the food and fodder - soldiers, slaves or animals - needs to eat as well, thus capping the possible reserve of food for the entire army at several weeks.
(This didn't apply on water where food and provisions could be shipped. This blog only analyzes movements over land.)
You will also learn why March is named after the Roman god of war (Mars). Again, it is military logistics. And why the American Constitution has by-now uncontroversial Third Amendment, which addresses a topic that used to be very, very painful for people right up to the 18th century.
