Through naval bombardments of Cretan insurgent forces, by placing sailors and marines ashore to occupy key cities, and by establishing a blockade of Crete and key ports in Greece, the International Squadron brought organized fighting on Crete to an end by the end of March 1897, although the insurrection continued. Soldiers from the armies of five of the powers (Germany declined to send any) arrived to occupy key Cretan cities in late March and April 1897. Thereafter, the Admirals Council focused on a negotiated settlement that would bring the insurrection to an end without bringing Ottoman governance of Crete to an end, but this proved impossible. They then decided that Crete would become an autonomous state under the suzerainty of the Ottoman Empire. Germany strongly opposed this idea and withdrew from Crete and the International Squadron in November 1897 and Austria-Hungary followed in March 1898, but the remaining four powers carried on with their plans. On 6 September 1898 (25 August 1898 according to the Julian calendar then in use on Crete, which was 12 days behind the modern Gregorian calendar during the 19th century), a Cretan Muslim mob massacred hundreds of Cretan Greeks and murdered the British vice-consul, his family, and 14 British soldiers and sailors, in the city of Candia (modern Heraklion). As a result, the International Squadron and the occupying forces ashore expelled all Ottoman forces from Crete in November 1898. The autonomous Cretan State, under Ottoman suzerainty, garrisoned by an international military force, and with its high commissioner provided by Greece, was founded when Prince George of Greece and Denmark arrived to take office as the first high commissioner (, "Hýpatos Harmostēs"), effectively detaching Crete from the Ottoman Empire, on 21 December 1898 (9 December according to the Julian calendar). The Admirals Council was dissolved on 26 December 1898. The National Bank of Greece established a bank, the Bank of Crete, which had a 40-year monopoly on note issuance. The Cretan State also established a paramilitary force, the Cretan Gendarmerie, modeled on the Italian Carabinieri, to maintain public order. The Cretan Gendarmerie incorporated the four small gendarmerie units the four remaining occupying powers had created before the arrival of Prince George. On 13 December 1898, Prince George of Greece and Denmark arrived as high commissioner for a three-year tenure. On 27 April 1899, an Executive Committee was created, in which a young, Athens-trained lawyer from Chania, Eleftherios Venizelos, participated as minister of justice.
