Also in October, several fortifications were built on Sonderbund territory, notably in Valais, where Kalbermatten's forces were massed by the end of October between Saint-Maurice and Saint-Gingolph, with a view of invading the Chablais of Vaud.
Oktoobris ehitati Sonderbundi territooriumile ka mitu kindlust, peamiselt Valais's, kus Kalbermatteni väed kogunesid oktoobri lõpuks Saint-Maurice ja Saint-Gingolph vahele, eesmärgiga tungida Chablais'sse Vaud's.
