Armies could only pass through even low mountains by following what few natural routes existed. In this eastern portion of the Erzgebirge, that meant following the Elbe, the same river that was dominated by Tetschen here.
Tetschen's second great advantage was that it was a relatively large town. Not a city, certainly. But it was very far from a country village, too. It was large enough to provide a base for a regiment, without requiring constant foraging in the countryside. "Foraging" was military-speak for requisitioning supplies by methods which were often nothing more than legalized plunder. Given that the lands said regiment would be plundering were Czech lands ruled by the very same Wallenstein that Mike and his Third Division had been sent to support, that could get very dicey, very quickly.
But with a town the size of Tetschen, Mike was pretty sure that one of his regiments would be able to get its supplies without overly aggravating the area's residents. That was especially true of the regiment he had in mind for the task.
Finally, Tetschen was very close to Dresden. As the crow flies, probably not more than thirty miles. Mike wasn't sure yet-he wasn't sure at all, actually-but that might turn out to be critical.
