He and 'Chinese' Gordon of Khartoum were the last of the great British imperial officers.
Seconded by Britain to its protectorate, the Hashemite Kingdom of Jordan, Glubb built up its small Bedouin army, the Arab Legion, into the Arab world's finest military force.
Glubb's Arab Legion would likely have defeated Israel's forces in the 1948 Arab-Israeli War had Britain and Jordan's double-dealing king Abdullah not blocked the Legion's advance, as Glubb Pasha bitterly recalled in his memoires.
When asked which of his many medals and honors he valued most, Glubb surprisingly replied , "Defender of the Shepherds of Iraq, " This obscure award was conferred upon Glubb by the King of Iraq when Sir John commanded the Iraq Border Constabulary during the 1930's.
Glubb Pasha and his men had waged a long campaign against the Ikhwan of Saudi Arabia. The Ikhwan (Brotherhood) was a collection of fanatical Saudi tribesmen imbued with the puritan desert creed of Wahabism. They saw all non-Wahabi Muslims as infidels (kufr), fair game to be robbed or killed. Even the king of Saudi Arabia failed to control the marauding Ikhwan.
