The Imperial army tried on one side to force the Tonale Pass and enter Lombardy, on the other side to make two converging thrusts into central Venetia, the first one southeastward from the Trentino, the second one southwestward across the lower Piave.
The name is derived from the type locality of tonalites, adjacent to the Tonale Line, a major structural lineament and mountain pass, Tonale Pass, in the Italian and Austrian Alps.
