Frederick sailed from Regensburg on 11 May 1189, but most of the army had left earlier by land for the Hungarian border. On 16 May, Frederick ordered the village of Mauthausen burned because it had levied a toll on the army. In Vienna, Frederick expelled 500 men from the army for various infractions. He celebrated Pentecost on 28 May encamped across from Hungarian Pressburg. During his four days encamped before Pressburg, Frederick issued an ordinance for the good behaviour of the army, a "law against malefactors" in words of one chronicle. It apparently had a good effect.
