The Palestinian Arabs, the neighbouring Arab states, the promise of the expansion of territory and the goal to conquer Jerusalem finally pressured Abdullah into joining them in an "all-Arab military intervention" on 15 May 1948. He used the military intervention to restore his prestige in the Arab world, which had grown suspicious of his relatively good relationship with Western and Jewish leaders. Abdullah was especially anxious to take Jerusalem as compensation for the loss of the guardianship of Mecca, which had traditionally been held by the Hashemites until Ibn Saud seized the Hejaz in 1925. Abdullah's role in this war became substantial. He distrusted the leaders of the other Arab nations and thought they had weak military forces; the other Arabs distrusted Abdullah in return. He saw himself as the "supreme commander of the Arab forces" and "persuaded the Arab League to appoint him" to this position. His forces under their British commander Glubb Pasha did not approach the area set aside for the Jewish state, though they clashed with the Yishuv forces around Jerusalem, intended to be an international zone. According to Abdullah el-Tell it was the King's personal intervention that led to the Arab Legion entering the Old City against Glubb's wishes.
