In 1402/3 Schwyz signed an alliance with Appenzell, which was seeking independence from the Abbey of St. Gall. In May 1403, the Abbot and the Habsburgs sent a force to defeat the rebellious Appenzellers while Schwyz and Glarus sent troops to defend their ally. On 15 May 1403, the Abbot's forces entered the pass leading to Speicher, and outside the village of Vögelinsegg they met the Appenzell army. A detachment of about 80 Appenzellers started the attack from a hill over the valley, with about 300 soldiers from Schwyz and 200 from Glarus moving around the flanks of the army. When the League's cavalry charged up the hill, they met 2000 Appenzellers and were forced to retreat. During the retreat, about 600 horsemen and many of the 5000 infantry were killed by the Appenzell army. The League signed a peace treaty with Appenzell at Arbon, but the peace was short-lived. Appenzell formed an anti-Habsburg alliance, the "Bund ob dem See", with several cities including Bregenz. In 1408 the Habsburgs besieged Bregenz, and the "Bund", including Schwyz, marched out to support Bregenz. However, when they met the Habsburgs, the "Bund" was decisively defeated and the "Bund" collapsed. Schwyz paid the Habsburgs off to avoid an attack and Appenzell retained some independence but eventually became an associate of the Confederation.
