«Flag of Denmark». The Danish flag, also called “Dannebrog” (it means “Danish cloth” in English), consists of a red background and white cross which extends to the edges of the flag. The vertical arm of the cross follows the model of the other Scandinavian flag thus; it is located closer to the left side of the flag. According to the legend, the flag was sent down from heaven in order to help the Danish army on June 15, 1219 during the Battle of Lyndanisse. King Valdemar II would nearly lose the battle against the pagan Estonians, if there was not a sign from heaven that gave the army new energy that helped them to win the battle. The flag is also used in a little bit modified version as a naval flag – it is square and it has two little flags similar to swallowtail. Source: http://flagpedia.net/denmark
