Why did many Crusaders oppose Richard I’s plan to attack Egypt?

During the Third Crusade, Richard I proposed attacking Egypt to strike at the power base of Saladin. However, this strategy was rejected by most of the Crusaders because they were deeply frustrated by Richard’s refusal to lay siege to Jerusalem.12

Although Richard’s decision to avoid a siege was tactically sound—as he recognized that he could not hold the holy city without control of the surrounding hinterland—it was bitterly unpopular among the rank and file of his army. Consequently, the Crusaders rejected his suggestion to shift the focus of the campaign to Egypt.12
