During the Battle of Lindanise the legend says that whenever Bishop Sunesen raised his arms the Danes surged forward and when his arms grew tired and he let them fall the Estonians turned the Danes back. Attendants rushed forward to raise his arms once again and the Danes surged forward again. At the height of the battle Bishop Sunsen prayed for a sign and it came in the form of a red cloth with a white cross which drifted down from the sky just as the Danes began to fall back. A voice was heard to say "When this banner is raised on high, you shall be victorious!" The Danes surged forward and won the battle. At the end of the day thousands of Estonians lay dead on the field, and Estonia was added to the Danish realm. Estonians were forcibly baptised as Christians, but according to an in depth study of the Liber Sencus Daniæ by the historian Edgar Sachs, the Estonians quite voluntarily converted to the Christian faith.
