Mosel was to leave Troppau June 26th; Ziethen pushes out to meet him from the Olmutz end, on the second day after; and, one hopes, all is now safe on that head.
The driving of 3,000 four-horse wagons, under escort, ninety miles of road, is such an enterprise as cannot readily be conceived by sedentary pacific readers;--much more the attack of such! Military science, constraining chaos into the cosmic state, has nowhere such a problem.
There are twelve thousand horses, for one thing, to be shod, geared, kept roadworthy and regular; say six thousand country wagoners, thick-soled peasants: then, hanging to the skirts of these, in miscellaneous crazy vehicles and weak teams, equine and asinine, are one or two thousand sutler people, male and female, not of select quality, though on them, too, we keep a sharp eye.

The series covers many miles, as many as twenty English miles (says Tempelhof), unless in favorable points you compress them into five, going four wagons abreast for defence's sake.

Defence, or escort, goes in three bulks or brigades; vanguard, middle, rear-guard, with sparse pickets intervening;--wider than five miles, you cannot get the parts to support one another.

An enemy breaking in upon you, at some difficult point of road, woody hollow or the like, and opening cannon, musketry and hussar exercise on such an object, must make a confused transaction of it! Some commanders, for the road has hitherto been mainly pacific, divide their train into parts, say four parts; moving with their partial escorts, with an interval of one day between each two: this has its obvious advantages, but depends, of course, on the road being little infested, so that your partial escort will suffice to repel attacks.

Toiling forward, at their diligent slow rate, I find these trains from Troppau take about six days (from Neisse to Olmutz they take eleven, but the first five are peaceable [Tempelhof, ii.
