An apporaching column has the sense to deloy from that, and with deploying I don't mean to deploy in line but to form a line of battle (in fact two lines minimum) with e.b. battalion cloumns (of peloton frontage, or divisional frontage, or colonne d'attaque, or even form the traditional battle line)

You put too much emphisize on the word typical (in Art's response).

An approaching column is not destined to fight tactical but to achieve deployment, as Ney describes, in case you look in the 1791 regulation you will find lots of approaching columns - the "only" difference to Ney is - that they would be used to deploy all battalions in line, whereas Ney would keep his tactical units in columns (of battalion or division. And he would form two lines of battle in columns not deployed into line.

Now when he has established those two lines of battalions, he could furhter deploy - on need - some of the battalion columns into line or keep them in column (as tactical formation and not longer as apporaching formation.

Steve put up a nice link of the English translation of Ney instructions, those helped me a lot to understand that system.

I agree with Art that such kind of approaching columns (mybe even of brigades or divisions) would be typical to deploy into tactical columns, see also again the 1791 regulations.
