Yeah but they kept Jerusalem during the third crusade, it was after the third crusade that the christians managed to retake jerusalem in the sixth crusade, when the Ayyubids were in civil war.

Though it was under conditions like it having no defenses and the muslims retaining control over the muslim holy places like Al-Aqsa.

After this one of the claimants of the Ayyubid throne fought the battle of Forbie destroying not only the crusader army, but the claimaint who allied them.

This was what caused the crusades to never take jerusalem again, and the mamluke sultanate that succeeded the Ayyubids cleaned up whatever was left of the kingdom of Jerusalem.

So basically the meme overstates the crusader effectiveness, they didn't succeed in taking jerusalem in the third crusade, and the sixth crusade led to them only holding it for a short time before their army was destroyed.
