Final answer:
The crusaders did not reach Beit Nuba during the Fifth Crusade; instead, they were entrapped in the Nile delta and withdrawn by 1221, reflecting the overall unsuccessful nature of that crusade.
Step-by-step explanation:
The crusaders never reached Beit Nuba during the Fifth Crusade. After capturing Damietta in 1219, the crusaders attempted to utilize the chaos following al-Adil I's death to claim further territories. The Muslim ruler al-Kamil offered Jerusalem and a thirty-year truce in exchange for the crusaders leaving Egypt, a deal the crusaders refused. This decision led to their entrapment in the Nile delta and their eventual withdrawal in 1221, thus marking another unsuccessful crusade.
Significant earlier crusader actions include the First Crusade's capture of Jerusalem in 1099, with a grave massacre of inhabitants, and the loss of Jerusalem again to Saladin in 1187, which prompted subsequent crusades including the Third and Fourth. By the end of the Fifth Crusade, the objective to reach Jerusalem, including passing through regions such as Beit Nuba, was unmet, illustrating the complicated and often failed endeavors of the crusader campaigns.
