Duke Leopold gathered his troops at Brugg, consisting of his feudal vassals from Swabia, the Alsace, Aargau, Thurgau, Tyrol, as well as bourgeois forces of various towns and Italian, French and German mercenaries. In the course of a few weeks, no less than 167 noblemen, both secular and of the church, declared war on the Swiss. These declarations were sent to the Swiss diet in 20 packets, in order to increase the effect of shock. On 24 June, a messenger from Württemberg brought 15 declarations of war. Before all letters had been read, the messenger from Pfirt delivered another eight, and before he had finished speaking, letters from the lords of Schaffhausen were brought in. Another eight messengers arrived on the following day.
