I am looking for a realistic start time for the Battle of Bar-sur-Aube, February 27, 1814.

Also info that would help to give me some idea as to where the Allied columns (Wittgenstein and Wrede) were when the battle started.

I know that Eugene was the lead infantry formation for the Russians. The cavalry under Pahlen ended up making a flank march through the woods and then out on to the plateau area.

Wrede marched probably in front of the Austrians with his Bavarians.

Hourtoulle in his 1814 book has a short account of the battle but does not state a start time nor does he give a column order for Wrede's V Corps.

Kretov's cuirassiers are mentioned in his account. I have to read more on that to determine just how much of his division was involved. Digby Smith does not list Kretov in his Russian forces listing on page 500 of his Data Book.
