I found it in the work on Russian tactics by the Zhmodikovs'. Their work is very well-sourced and I have no doubt they are correct.

Do you have a citation for Wilson and was it in his 1806-1807 work or his on 1812?

If you cannot cite it that's OK, I'll look it up and see if I can find it as I do have both volumes.

Sincerely,
K
