Soldiers were issued three pairs of shoes a year: one pair for summer, one for autumn, and one for winter.
In summer, they wore rubber-soled cloth shoes with socks and leggings.
In autumn, they wore military-issue, knee-high rubber-soled leather boots with thick socks and leggings.
In winter, they wore the same boots as in autumn, but with a wool interlayer. After the conquest of the Kingdom of Ivrea, cotton was added as another option.
Since they needed to wear thick trousers in winter, they didn't wear leggings. Instead, they needed thick socks and a thick foot cloth.
They were also given loose fabric, cotton, wool, and other materials to stuff around their feet themselves.
Their feet were already well protected.
But even that couldn't make up for long marches, especially when soldiers didn't wash their feet, lacked basic hygiene knowledge, and spent all day on the move.
Lynn took one city a day, frequently redeploying his troops. The army was often on long marches.
Lynn's usual method was to send one unit to attack a city, then have the next regular unit due to attack move toward the following target city. The march usually took two days, with the attack taking place on the second day.
The magic railway construction units in the rear also did their best to build railways.
But most of the time, they still relied on Devil Beast Horses for logistical supplies.
So, how many kilometers did Lynn's army march in a day?
An average of 25 kilometers a day.
There was another counterintuitive fact about Lynn's army.
The Infantry Division marched an average of just 25 kilometers a day purely because of the heavy artillery units.
Devil Beast Horses were basically all thoroughbreds capable of covering a thousand li. After all, they were magical beasts.
