In 1158 a feud with Henry the Lion, Duke of Saxony, was interrupted by a pilgrimage to the Holy Land. On his return in 1160, he, with the consent of his sons, Siegfried not being mentioned, donated land to the Knights of Saint John in memory of his wife, Sofia, at Werben on the Elbe.[4][5][6] Around this same time, he minted a pfennig in memory of his deceased wife.[citation needed] In 1162 Albert accompanied Emperor Frederick Barbarossa to Italy, where he distinguished himself at the storming of Milan.[3]
