They either die of starvation or they get sold into slavery on the way. Historians today aren't sure whether it really happened as that account implies. That's why I put these question mark next to the Children's Crusade. But regardless of the actual facts here, as we go into the first quarter of the 13th century, Jerusalem remains in the hands of the Muslims. A fifth crusade is launched to retake Jerusalem, which is a failure. Eventually, a sixth crusade is launched, and this is reasonably successful at retaking some land in the Holy Land, but shortly thereafter, you have a non-numbered crusade, the Barons' Crusade, that rivals the first crusade in its success in taking territory. And so you can see, after the Barons' Crusade right over here, they're able to take back a good amount of territory.
