as part of the leadership of the Organization Delchev's involvement in BMARC was an important moment in the history of the Macedonian-Adrianople liberation movement. The years between the end of 1896, when he left the Exarchate's educational system and 1903 when he died, represented the final and most effective revolutionary phase of his short life. In the period 1897–1902 he was a representative of the Foreign Committee of the BMARC in Sofia. Again in Sofia, negotiating with suspicious politicians and arms merchants, Delchev saw more of the unpleasant face of the Principality, and became even more disillusioned with its political system. In 1897 he, along with Gyorche Petrov, wrote the new organization's statute, which divided Macedonia and Adrianople areas into seven regions, each with a regional structure and secret police, following the Internal Revolutionary Organization's example. Below the regional committees were districts. The Central committee was placed in Thessaloniki. In 1898 Delchev decided to be created a permanent acting armed bands (chetas) in every district. From 1902 till his death he was the leader of the chetas, i.e. the military institute of the Organization because, he had considerable knowledge in the area of military skills. Delchev ensured the functioning of the underground border crossings of the organization and the arms depots added to them, alongside the then Bulgarian-Ottoman border. His correspondence with other BMARC/SMARO members covers extensive data on supplies, transport and storage of weapons and ammunition in Macedonia. Delchev envisioned independent production of weapons, and traveled in 1897 to Odessa, where he met with Armenian revolutionaries Stepan Zorian and Christapor Mikaelian to exchange terrorist skills and especially bomb-making. That resulted in the establishment of a bomb manufacturing plant in the village of Sabler near Kyustendil in Bulgaria. The bombs were later smuggled across the Ottoman border into Macedonia. Gotse Delchev was the first to organize and lead a band into Macedonia with the purpose of robbing or kidnapping rich Turks. His experiences demonstrate the weaknesses and difficulties which the Organization faced in its early years. Later he was one of the organizers of the Miss Stone Affair. He made two short visits to the Adrianople area of Thrace in 1896 and 1898. In the winter of 1900 he resided for a while in Burgas, where Delchev organized another bomb manufacturing plant, which dynamite was used later by the Thessaloniki bombings. In 1900 he inspected also the BMARC's detachments in
