March rates for armies

[Sean Manning]

Rhoads Murphy's Ottoman Warfare 1500-1700 also has lots of good figures. The Ottomans managed to break some of the usual rules, like being able to muster 50,000 horse at the start of a campaign and mobilize half or more of their army for an annual campaign. But when their major armies were on the march they made the same 12-15 miles per day of marching (not rest, halt for bridge-building, etc.) that other good armies did.
