Cpl/sgt Robert Gregory - present at Kioge?

I recently aquired this medal to Serjeant Robert Gregory from Salford, Lancastershire.

As you can see he served in Egypt, Matinique and the peninsula campaign. He also was present and wounded at Waterloo.

Among his unmedaled merit was service in Canada and possibly service in Denmark in 1807 at Køge/Kioge.

Would there be any records in the museum to show if he was present in Denmark or any other record of his service? Possibly his Waterloo medal in the museum?http://rwf-forum.co.uk/vBulletin/att...tid=5624&stc=1
