At around midnight on 20/21 October, putschists of the 11th Armoured Car Battalion departed from Camp Muha in over a dozen armoured cars and took up positions around Bujumbura. Within an hour they surrounded the Presidential Palace. They were joined by hundreds of soldiers and gendarmes from the other eleven military camps in Bujumbura, including members of the 1st Parachute Battalion and a few personnel from the 2nd Commando Battalion. They prepared to attack the palace, which was only guarded by 38 soldiers of the Presidential Guard and two armoured cars. Shortly before 01:00 on 21 October, Ntakije called the president and told him that armoured cars had left Camp Muha for an unknown destination and advised him to leave the palace immediately. Ndadaye then attempted to reach Captain Ildephonse Mushwabure, the commander of the palace guard, by phone, but when he did not answer he went into the palace gardens. At 01:30 the putschists fired a single shot, and shortly thereafter at least one armoured car blasted a hole in the wall of the grounds and began bombarding the palace with cannon fire. Laurence Ndadaye took her three children into an interior room and sheltered them under tables, though she and her son were grazed by shrapnel. Meanwhile, the president was disguised in a military uniform by his guards and placed in one of their armoured cars in the garden, where he remained for the next six hours. According to political scientist René Lemarchand, the palace guards offered sustained resistance to the attack until several of them defected to the increasing number of putschists and the rest gave up. Two of the putschists were reportedly wounded by gunfire when they attempted to enter the palace grounds. In contrast, Laurence Ndadaye stated that none of the guards resisted the attack. The United Nations International Commission of Inquiry for Burundi wrote, "An armed confrontation is reported to have taken place between 'attackers' and 'defenders' for six hours...yet no one was killed, no armored car damaged." Laurence Ndadaye was unable to reach her husband's cell phone and believed he was dead. When Ntakije called for him, she told him that he was in the garden. Laurence then made a series of phone calls to Minister of Foreign Affairs Sylvestre Ntibantunganya, Minister of Agriculture Cyprien Ntaryamira, FRODEBU leaders, the provincial governors, and President Juvénal Habyarimana of Rwanda to inform them of the coup.
