Innocent had still much trouble with the Antipope, and his chief supporter, Roger of Sicily. He soon withdrew from Rome to Pisa, where, in 1134, he held a synod, which Bernard left Clairvaux to attend. But not even the animating presence of the saint could make Anacletus and Roger submit. Innocent was forced to continue at Pisa until, in 1136, Lothair crossed the Alps a second time to help him. On this occasion the Emperor came with an army, and St. Bernard’s fervid denunciations of the Norman tyrant, who alone upheld to any purpose the schismatic cause, gave the expedition the character of a crusade. Lothair performed exploits, said Otto of Freising, in Calabria and Apulia such as no Frankish king had done since the days of Charles the Great. He captured some of the chief Norman towns, such as Bari and Salerno, while the fleets of Pisa made precarious the communication between Calabria and Sicily. Roger, after striving in vain to bribe the Emperor into retreat, did not scruple to arm his Saracens against the two lords of the Christian world. He retreated into the mountains of Calabria, while the Pope and Emperor united in deposing him and conferring Apulia on Reginald, a prominent Norman baron of that region. But at the moment of victory Innocent and Lothair quarrelled. Both claimed to be the suzerains of Apulia, and both claimed the sole right of investing the new duke with his office. After a hot dispute, they agreed to hand over jointly to Reginald the banner, which was the symbol of his dignity; but before long Lothair hurried home, disgusted with his Papal ally, and leaving Anacletus again in possession of Rome. The fatigues of war and travel told upon him, and he died at a Tyrolese village on 4th December 1137, saved only by death from entering upon the footsteps of the Salian enemies of the Church.
