On the matter of force levels for the war, the Piedmontese military commander Alfonso Ferrero La Marmora had produced a plan involving an army of 160,000 men, provided 50:50 by France and Piedmont-Sardinia, and a military campaign focused on the Po Valley. The emperor had his own plan, however, involving 300,000 men of whom 200,000 would be French, and he spoke in terms of a military campaign pushing right through to Vienna.[1]
