"Toll," vol. i., pp. 256 et seq. Müffling was assured by Phull in 1819 that the Drissa plan was only part of a grander design which had never had a fair chance!
Bernhardi's "Toll" (vol. i., p. 231) gives Barclay's chief "army of the west" as really mustering only 127,000 strong, along with 9,000 Cossacks; Bagration, with the second "army of the west," numbered at first only 35,000, with 4,000 Cossacks; while Tormasov's corps observing Galicia was about as strong. Clausewitz gives rather higher estimates.
Labaume, "Narrative of 1812," and Ségur.
See the long letter of May 28th, 1812, to De Pradt; also the Duc de Broglie's "Memoirs" (vol. i., ch. iv.) for the hollowness of Napoleon's Polish policy. Bignon, "Souvenirs d'un Diplomate" (ch. xx.), errs in saying that Napoleon charged De Pradt—"Tout agiter, tout enflammer." At St. Helena, Napoleon said to Montholon ("Captivity," vol. iii., ch. iii.): "Poland and its resources were but poetry in the first months of the year 1812."
