When it became clear that President Ngo Dinh Diem had no intention of holding elections for a united Vietnam, his political opponents began to consider alternative ways of obtaining their objectives. Some came to the conclusion that violence was the only way to persuade Diem to agree to the terms of the 1954 Geneva Conference. The year following the cancelled elections saw a large increase in the number of people leaving their homes to form armed groups in the forests of Vietnam. At first they were not in a position to take on the South Vietnamese Army and instead concentrated on what became known as 'soft targets'. In 1959, an estimated 1,200 of Diem's government officials were murdered.
