The King himself at the head of 35,000 men, supported by Prince Maurice and the States' forces amounting to at least 14,000, would move to the Rhine and seize the duchies.

The Duke de la Force would command the army of the Pyrenees and act in concert with the Moors of Spain, who roused to frenzy by their expulsion from the kingdom could be relied on for a revolt or at least a most vigorous diversion.

Thirdly, a treaty with the Duke of Savoy by which Henry accorded his daughter to the Duke's eldest son, the Prince of Piedmont, a gift of 100,000 crowns, and a monthly pension during the war of 50,000 crowns a month, was secretly concluded.
Early in the spring the Duke was to take the field with at least 10,000 foot and 1200 horse, supported by a French army of 12,000 to 15,000 men under the experienced Marshal de Lesdiguieres.

These forces were to operate against the Duchy of Milan with the intention of driving the Spaniards out of that rich possession, which the Duke of Savoy claimed for himself, and of assuring to Henry the dictatorship of Italy.

With the cordial alliance of Venice, and by playing off the mutual jealousies of the petty Italian princes, like Florence, Mantua, Montserrat, and others, against each other and against the Pope, it did not seem doubtful to Sully that the result would be easily accomplished.
