Borngen and L. D. Schmadel at Tautenburg. Innkeeper Andreas Hofer (1767-1810) headed the Tyrolese popular rising against French occupation and was executed by a firing squad on order of Napoleon. His patriotic and heroic engagement is the subject of numerous dramatic plays, stories and poems, notably by Rosegger, Eichendorff and Koerner.
