Zwingli's far-reaching plans included an alliance with Hesse and with Francis I to whom he dedicated his {158} two most important theological works, _True and False Religion_ and _An Exposition of the Christian Faith_.

[Sidenote: April, 1529] The Catholic cantons replied by making a league with Austria.

War seemed imminent and Zwingli was so heartily in favor of it that he threatened resignation if Zurich did not declare war.

This was accordingly done on June 8.
Thirty thousand Protestant soldiers marched against the Catholic cantons, which, without the expected aid from Austria, were able to put only nine thousand men into the field.

Seeing themselves hopelessly outnumbered, the Catholics prudently negotiated a peace without risking a battle.
