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. 48.]);--can't be hurried beyond that pace, if you would save your laggards, your irregulars, and prevent what we may call RAGGERY in your rearward parts; the skirts of your procession get torn by the bushes if you go faster. This time Colonel Mosel will have to mend his pace, however, and to go in the lump withal; the case being critical, as Mosel knows, and MORE than he yet knows. Daun, who has friends everywhere, and no lack of spies in this country, generally hears of the convoys. He has heard, in particular, of this important one, in good time. Hitherto Daun had not attempted much upon convoys, nor anything with success: King's posted corps and other precautions are of such a kind, not even Loudon, when he tried his best, could do any good; and common wandering hussar parties are as likely to get a mischief as to do one, on such service. Cautious Daun had been busy enough keeping his own Camp safe, and flinging a word of news or encouragement, at the most a trifle of reinforcement, into Olmutz. when possible. But now it becomes evident there must be one of two things: this convoy seized, or else a battle risked;--and that in defect of both these, the inevitable third thing is, Olmutz will straightway go.
