Thiers has shown that Mortier did not get the order from Berthier to support Vandamme until August 30th. The same is true of St. Cyr, who did not get it till 11.30 a.m. on that day. St. Cyr's best defence is Napoleon's letter of September 1st to him ("Lettres inédites de Napoléon"): "That unhappy Vandamme, who seems to have killed himself, had not a sentinel on the mountains, nor a reserve anywhere.... I had given him positive orders to intrench himself on the heights, to encamp his troops on them, and only to send isolated parties of men into Bohemia to worry the enemy and collect news." With this compare Napoleon's approving statement of August 29th to Murat ("Corresp.," No. 20486): "Vandamme was marching on Teplitz with all his corps."

Häusser, vol. iv., p. 343, and Boyen, "Erinnerungen," vol. ii., pp. 345-357, for Bernadotte's suspicious delays on this day; also Marmont, bk. xviii., for a critique on Ney. Napoleon sent for Lejeune, then leading a division of Ney's army, to explain the disaster; but when Lejeune reached the headquarters at Dohna, south of Dresden, the Emperor bade him instantly return—a proof of his impatience and anger at these reverses.
[Footnote 367: Thornton, our envoy at Bernadotte's headquarters, wrote to Castlereagh that that leader's desire was to spare the Swedish corps; he expected that Bernadotte would aim at the French crown ("Castlereagh Papers," 3rd series, vol. i., pp. 48-59). See too Boyen, vol. ii., p. 378.]
