This medal is driving me insane! I have looked and looked for this man and can not find him. There were fewer than 100 Brunswick officers with the "Owls" in Spain and a great many, those who were not British, ended up at Waterloo. They were hard core Brunswick loyalists. The Oels, or "Owls" as the Brits called them, were 12 companies strong, but their rifle companies were detached and used as permanent skirmishes in other British or mixed Divisions.
At Vittoria, 9 center companies were assigned as a weak battalion to the 7th Division, which attacked the center of the vastly over stretched French lines moving down from the steep heights towards the bridge crossing the river. the 7th was barely engaged in the battle and Surgeon Breyer was almost certainly attached to the Divisional hospital and perhaps that is why he had no other clasps, as usually the Brunswickers had 3-5 surgeons. There is a chance he was not German at all, as many other British and other foreigners served in the battalion. They were notorious for desertion, but the hard core of Brunswickers made up an elite and very tough fighting unit.
