Maitland's "Narrative," p. 222. Basil Jackson, who knew Gourgaud well at St. Helena, learnt from him that he could not finish his account of Waterloo, "as Napoleon could never decide on the best way of ending the great battle: that he (Gourgaud) had suggested no less than six different ways, but none were satisfactory" ("Waterloo and St. Helena," p, 102). Gourgaud's "Journal" shows that Napoleon blamed in turn the rain, Ney, Grouchy, Vandamme, Guyot, and Soult; but he ends—"it was a fatality; for in spite of all, I should have won that battle."
