The original website "mémoire des hommes" is unavailable right now : i think it will be possible to see the original document from there... VANTHOELOND is perhaps a wrong transcription
Edit : sorry Claudine... I didn't see your message
See here and click on the litte magnifying glass on the right side : https://search.arch.be/fr/rechercher-des-personnes/resultats/q/persoon_achternaam_t_0/van%20toelant/q/persoon_voornaam_t_0/jean%20baptiste/q/zoekwijze/s?M=0&V=0&O=0&persoon_0_periode_geen=0
This is a document from the belgian state archives : it states that a soldier called Jean Baptiste Van Toelant was replaced in 1806 by another guy called Jean Baptiste De Gres
That is the site that I mentioned showing Jean Baptiste De Gres. I tried to access the site that you sent but it seemed to be down. Can you tell me what information I need to put in to do a search? I really appreciate these little tidbits of information. So exciting!
The website I was talking about is back!
It confirms what was said before: your ancestor was nicknamed Vanthoelond as he replaced somene called that name...
