He was strong, tough and fought with his men, the enemy did'nt know what to think.
He never captured Jerusalem on the third crusade because he was clever enough to realise that once it was captured, there would not be enough men to defend it, just like after the first crusade. However he did hold on to Acre and Jaffa, he also secured Christian pilgrims safe passage to the Holy land.
If only he had not have died in 1199
then King John might never have started his evil 
reign.
