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, Upper Austria|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 [[Bratislava|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.{{sfn|Freed|2016|pp=488–489}}

From Pressburg, the Hungarian envoys escorted the crusaders to [[Esztergom]], where King [[Béla III of Hungary]] greeted them on 4 June. He provided boats, wine, bread and barley to the army. Frederick stayed in Esztergom for four days. The king of Hungary accompanied the army to the Byzantine border at [[Belgrade]]. There were incidents during the crossing of the [[Drava]] and [[Tisza]] rivers, but the [[Sava]] was crossed on 28 June without incident. In Belgrade, Frederick staged a tournament, held a court, conducted a census of the army and wrote to the Byzantine emperor [[Isaac II Angelos|Isaac II]] to inform him that he had entered Byzantine territory.{{sfn|Freed|2016|pp=489–490}}
