GOTHA, 18th SEPTEMBER. "Since Thursday 15th, Major-General Seidlitz," youngest Major-General of the Army, but a rapidly rising man, "has been Commandant in Gotha, under flourishing circumstances; popular and supreme, though only with a force of 1,500, dragoons and hussars. Monday morning early, Seidlitz's scouts bring word that the Soubise-Hildburghausen people are in motion hitherward; French hussars and Austrian, Turpin's, Loudon's, all that are; grenadiers in mass;--total, say, 8,000 horse and foot, with abundance of artillery;--have been on march all night, to retake Gotha; with all the Chief Generals and Dignitaries of the Army following in their carriages, for some hours past, to see it done. Seidlitz, ascertaining these things, has but one course left,--that of clearing himself out, which he does with orderly velocity: and at 9 A.M. the Dignitaries and their 8,000 find open gates, Seidlitz clean off; occupy the posts, with due emphasis and flourish; and proceed to the Schloss in a grand triumphant way,--where privately they are not very welcome, though one puts the best face on it, and a dinner of importance is the first thing imperative to be set in progress. A flurried Court, that of Gotha, and much swashing of French plumes through it, all this morning, since Seidlitz had to flit. "Seidlitz has not flitted very far. Seidlitz has ranked his small dragoon-hussar force in a hollow, two miles off; has got warning sent to a third regiment within reach of him, 'Come towards me, and in a certain defile, visible from Gotha eastward, spread yourselves so and so!'--and judges by the swashing he hears of up yonder, that perhaps something may still be done. Dinner, up in the Schloss, is just being taken from the spit, and the swashing at its height, when--'Hah what is that, though?' and all plumes pause. For it is Seidlitz, artistically spread into single files, on the prominent points of vision; advancing again, more like 15,000 than 1,500: 'And in the Defile yonder, that regiment, do you mark it; the King's vanguard, I should say?--To horse!'
