I'm afraid, that no matter where I check, I cannot find any reference to anyone named Eleazar during the Crusades.
No..the crusades were intended to capture Jerusalem for Christianity and to oust the Moslems from there. The Jews suffered terribly during the crusades.

Crusades
The Crusades to the Holy Land all happened during the High Middle Ages. There were later military actions also called Crusades that happened in other places. An example was the Hussite Crusade, which happened in Central Europe during the period of 1420 to 1434.

I was not alive during the crusades.
Also known as: Eleazar Rokeach, Eleazar of Worms Eleazar ben Judah ben Kalonymus c. 1176-1238 (about 62) Eleazar ben Judah was most likely born in Mainz in 1176. He died at Worms in 1238. In November- December of 1196, two crusaders entered his house at night, killing his wife Dulcina, his two daughters Belat and Hannah, and his son Jacob. He was badly wounded but escaped alive. Years before, during the Second Crusade, he and other Jews were forced to flee town. The Crusades had a profound effect on his life. Eleazar wondered if his people would survive in Europe. Despite all his suffering due to the facts that he was a Jew, he continued to preach love for all humanity as a Jewish leader in the city of Worms, a city south of Mainz.
