Hugo II, Count of Werdenberg-Heiligenberg

Hugo II (died 1305 or 1309), called the One-Eyed, was count of Werdenberg-Heiligenberg and a loyal follower of the Habsburgs. In April 1292 he relieved Winterthur for Duke Albert I and then helped storm Wil after a two-month siege, where Albert knighted him.

He fought at Göllheim in 1298, when Albert took the crown from Adolf of Nassau. Married to Euphemia of Ortenburg, he is last documented in July 1305.
