Why did Hitler win the iron cross?

Some sources suggest that Adolf Hitler won the Iron Cross, 2nd Class for saving his officer's life at the First Battle of Ypres in 1914. In addition, he allegedly won the Iron Cross 1st Class for outstanding bravery in 1918. However, there is substantial evidence (www.guardian.co.uk/politics/1932/mar/09/thefarright.uk) that contradicts he ever won any medal and is likely that his military record was falsified by vainglorious political motivations.
