Rod,

Here is the part of Suchet's report to Lannes regarding the passage of lines:

'The 17th [Legere] was short on ammunition and was weakening. I ordered general Reille to replace it with the 34th [Ligne]. The passage of lines was executed perfectly by battalion, and at this point in time the sun began to dissipate the fog and we noticed at a short distance three battalions of grenadiers in grands bonnets, whom we struck in the flank.' -Suchet to Lannes at Weimar, 15 October 1806.
