work, digging tunnels in both places. On 18 September 1900 the Ottoman police apprehended a member of a group, who was carrying the explosives and later the whole group was arrested, including Merdjanov, Sokolov and Pavel Shatev. The core was hastily disbanded for security and only Pingov stayed in Thessaloniki to prepare future activity. In 1901 the prisoners were deported το Bulgaria, after pressure from the Bulgarian government. Attack plans and actions in Adrianople Merdzjanov and Sokolov went to Sofia and began to think up new ideas, one of which was to hold up the Orient Express on Ottoman territory near Adrianople, and to gain possession of the mail in order to finance future actions. In pursuit of this plan, they went to the Adrianople area in July 1901, with a cheta consisting of ten men, equipped with the help of Pavel Genadiev, the Supreme Macedonian Committee's representative in Plovdiv. The cheta managed to place a large quantity of dynamite on the railway line, but something went wrong, and the train passed undamaged. They learned then that the Persian Shah would pass through Adrianople by train, preparing to take him on the station at Lule Burgas, but failed. From there they headed to Adrianople with the intention of capturing the governor, who was the son-in-law of the Sultan, but failed again. After this failure, they kidnapped the son of a rich local Turkish landowner, but they were soon discovered and surrounded by large Turkish forces. In a battle which lasted several hours, most of the chetnitsi were killed or seriously wounded. Sokolov was among the dead, and Merdzjanov was captured alive, together with a Bulgarian from Lozengrad, and two Armenians. The captives were taken to Adrianople, where, in November 1901, all four were publicly hanged. The Gemidzhii were ready for action again in 1902, but the seizure in Dedeagach of dynamite, arranged by Supreme Macedonian Committee's leader Boris Sarafov, forced the group to abandon planned attacks of Austrian post office in Adrianople, and to restrict its activity. Afterwards the members of the group went to Thessaloniki and continued to plan their new bombings. Bombings in Thessaloniki On the 28 April 1903, a member of the group, Pavel Shatev, used dynamite to blow up the French ship "Guadalquivir" which was leaving the Thessaloniki harbour. The bomber left the ship together with the other passengers, but was caught later by the Turkish
