Joseph Hormayr zu Hortenburg, Freiherr von; C H Hall, Memoirs of the life of Andrew Hofer... (1820), p.166
This is not a history book either. What you seem to fail to understand is that much, if not all, accounts of the Tyrol of this era, especially the German ones, are German nationalist in origin and just cannot be taken at face value, as you are trying to do. This might be right or it might be wrong. It might be all myth.
Also, "Imperial Commandant", under the circumstances then, is in effect a regent. Imperial would a direct reference to the Imperial Monarch, Franz II/I. Hofer never would have rebelled against the legitimate government in Vienna.
