Here is a very curious fact and consideration. That the King had so prophesied and preordained: "May 4th, Four Columns arrive at Prag; May 6th, attack the Austrians, beat them,"--and now wished to keep his word! This is an aerial reason, which I can suspect to have had its weight among others. There were twirls of that kind in Friedrich; intricate weak places; knots in the sound straight-fibred mind he had (as in whose mind are they not?),--which now and then cost him dear! The Anecdote-Books say he was very ill of body, that day, May 6th; and called for something of drug nature, and swallowed it (drug not named), after getting on horseback. The Evening Anecdote is prettier: How, in the rushing about, Austrians now flying, he got eye on Brother Henri (clayey to a degree); and sat down with him, in the blessed sunset, for a minute or two, and bewailed his sad losses of Schwerin and others. Certain it is, the victory was bought by hard fighting; and but for the quality of his troops, had not been there. But the bravery of the Prussians was exemplary, and covered all mistakes that were made. Nobler fire, when did it burn in any Army? More perfect soldiers I have not read of. Platt-Teutsch fire--which I liken to anthracite, in contradistinction to Gaelic blaze of kindled straw--is thrice noble, when, by strict stern discipline, you are above it withal; and wield your fire-element, as Jove his thunder, by rule! Otherwise it is but half-admirable: Turk-Janissaries have it otherwise; and it comes to comparatively little. This is the famed Battle of Prag; fought May 6th, 1757; which sounded through all the world,--and used to deafen us in drawing-rooms within man's memory. Results of it were: On the Prussian side, killed, wounded and missing, 12,500 men; on the Austrian, 13,000 (prisoners included), with many flags, cannon, tents, much war-gear gone the wrong road;--and a very great humiliation and dispiritment; though they had fought well: "No longer the old Austrians, by any means," as Friedrich sees; but have iron ramrods, all manner of Prussian improvements, and are "learning to march," as he once says, with surprise not quite pleasant.
