On June 10, Gérard wrote to Soult with an update on his march:

the Vichery division will go and lodge,

and the fourteen, in Rocroy

and the Pêcheux division will go and lodge,
the twelve of June, in Mézières
and the thirteen, to Rocroy.

I will be in Rocroy on the 12th of June.
As I have had the honor to report to your Excellency on the seventh of this month, the Bourmont division will arrive at Rocroy on the thirteenth of June and the Grand Park on the sixteenth of June.

Gressot had been ordered to accelerate the 14th Cavalry Division, which was joining the Armée du Nord.  From meeting with Gressot, Gérard realized the error of his earlier orders, and thus he adjusted his entire corps to catch up with the lead division commanded by Bourmont.

It should also be noted that Gérard sent this report to Soult in Laon.
