the Arabs, and raided as far as Nicaea, sacking Ephesus. Basil's general, Christopher, defeated the Paulicians in 872, and the death of their leader, Chrysocheir, led to the definite subjection of their state. Basil was the first Byzantine emperor since Constans II (r. 641–668) to pursue an active policy to restore the Empire's power in the West. Basil allied with Holy Roman Emperor Louis II (r. 850–875) against the Arabs and sent a fleet of 139 ships to clear the Adriatic Sea of their raids. With Byzantine help, Louis II captured Bari from the Arabs in 871. The city eventually became Byzantine territory in 876. However, the Byzantine position on Sicily deteriorated, and Syracuse fell to the Emirate of Sicily in 878. This was ultimately Basil's fault as he had diverted a relief fleet from Sicily to haul marble for a church instead. Although most of Sicily was lost, the general Nikephoros Phokas (the Elder) succeeded in taking Taranto and much of Calabria in 880. The successes in the Italian peninsula opened a new period of Byzantine domination there. Above all, the Byzantines were beginning to establish a strong presence in the Mediterranean Sea, and especially the Adriatic. Last years and succession Basil's spirits declined in 879, when his eldest and favorite son Constantine died. Basil now raised his youngest son, Alexander, to the rank of co-emperor. Basil disliked the bookish Leo, on occasion physically beating him; he probably suspected Leo of being the son of Michael III. In his later years, Basil's relationship with Leo was clouded by the suspicion that the latter might wish to avenge the murder of Michael III. Leo was eventually imprisoned by Basil after the detection of a suspected plot, but the imprisonment resulted in public rioting; Basil threatened to blind Leo but was dissuaded by Patriarch Photios. Leo was eventually released after the passage of three years. Basil died on 29 August 886, from a fever contracted after a serious hunting accident when his belt was caught in the antlers of a deer, and he was allegedly dragged 16 miles through the woods. He was saved by an attendant who cut him loose with a knife, but he suspected the attendant of trying to assassinate him and had the man executed shortly before he himself died. One of the first acts of Leo VI as ruling emperor was to rebury, with great ceremony,
