Gourgaud (ch. vi.) states that the time of Lobau's move was 4.30, though he had reconnoitred on his right earlier. Napoleon's statements on this head at St. Helena are conflicting. One says that Lobau moved at 1.30, another at 4.30. Perhaps Janin's statement explains why Lobau did nothing definite till the later hour.
Baring's account ("King's German Legion," App. xxi.) shows that the farm was taken about the time of the last great cavalry charge. Kennedy (p. 122) and Ompteda (ad fin.) are equally explicit; and the evidence of the French archives adduced by Houssaye (p. 378) places the matter beyond doubt.
