Bulgaria, Serbia, Greece and Montenegro cooperated because hostility to the Ottoman Empire outweighed their mutual distrust. Their quarrel over the rewards of victory then led to the Second Balkan War. Greece's contribution combined land forces with a fleet able to prevent Ottoman reinforcement through the Aegean. During negotiations, the Greek ambassador argued that Greece could contribute the equivalent of 600,000 men: 200,000 on the battlefield and another 400,000 Ottoman troops prevented from landing between Salonica and Gallipoli. This was an argument for the fleet's strategic value during alliance negotiations. Greek naval forces also captured islands using personnel and infrastructure developed through the reform programme.
