Match the crusade with the event

1. First Crusade - Siege of Jerusalem

2. Second Crusade - Battle of Hattin
3. Third Crusade - Treaty of Jaffa
4. Fourth Crusade - Sack of Constantinople
5. Children's Crusade - Peaceful march to the Mediterranean Sea
(Note: The Children's Crusade is often considered a myth or exaggerated, and historical evidence for a large-scale children's crusade is sparse)
