Karadžić believed that Sarajevo, being the largest city and capital of Bosnia, was the "neck of a snake", the head of the snake being the country itself.9 Karadžić thought this meant that to get the head of a snake or the country as a whole, one must grab it by the neck, its strongest part, to gain as much control over the snake (the country) as possible. . This was also essential for the planned ethnic cleansing, due to the ethnic diversity of Sarajevo, similar to that of the city of Srebrenica. The city of Sarajevo was put under lockdown, leaving around 400,000 people with limited supplies of food and water, and without a source of electricity for around 3 months. Guerrilla warfare also came into play, notably with the bombing of Red Cross trucks and maternity wards, killing many mothers and newborns10. However, on May 25, 1995, NATO planes destroyed the depots containing weapons and military equipment used to supply the Serbs. The siege did not officially end until February 29, 1996, although the last ceasefire occurred in October.
