With Broussier we do know that the 84e was formed in columns leading the right flank. Therefore it is quite probable that the 29e and 92e were deployed. The 9e followed the 84e in column
OdB according to Jack Gill
Broussier = 8 battalions
9e Ligne (three battalions)
84e Ligne (three battalions)
92e Ligne (only two of its battalions)
Lamarque = 12 battalions
18e Léger (two battalions)
13e Ligne (three battalions)
23rd Ligne (two battalions)
29e Ligne (three battalions)
92e Ligne (only two battalions--these two were attached, we do not know which brigade)
@Art - I cannot follow your argument, in case 29e and 92 are deployd - that would give us 5 battalions, instead of 8, so it could be that Lamarque deployed 13e and 23e de ligne and Broussier just his 92e de ligne, otherwise 84e could not be the lead regiment of the right column part, one must follow behind, which would leave only 8e de ligne.
For Lamarque the left ployed part woud be then 18e régiment d'Infanterie légčre, 23e and 92e de Ligne in column, making it 6 battalions in column versus 6 of Broussier as well.
