Howdy Pierre,
I think after Gohrde, Wallmoden's Corps moves to the north and is pretty much stationary until the Danes head home. They pursued the Danes in December, but in mid-January move back to Harburg for the blockade. By the end of the war, they are outside of Antwerp with the blockade.
Happy Holidays, Jerry
PS -- thanks for the kind words on the file I sent you. I've been adding quite a bit since then. Quistorp is invaluable even for a non-German speaker.
