1986–1990 Philippine coup attempts

The first occurred on 6 July 1986, when some 490 armed soldiers and 15,000 civilians loyal to former President Ferdinand Marcos occupied Manila Hotel for 37 hours.[1] At the hotel, Marcos's vice-presidential running mate Arturo Tolentino announced that Marcos had authorised him to temporarily take over the government, took his oath as Acting President, and designated a cabinet.[1] The public remained generally unaffected by this incident,[2] and it ended without violence by 8 July.[3]

A more serious conspiracy unfolded some months later, known as the "God Save the Queen Plot".[4] The Davide Commission concluded that Defense Secretary Enrile and members of the Reform the Armed Forces Movement (RAM) were behind the plot.[5] Scheduled for 11 November 1986, the plot was discovered by government several days in advance and was deliberately leaked to the Philippine Daily Inquirer, thus thwarting the plan.[6]

The government then learnt that the plot was rescheduled for 22 November 1986.[7] On November 22, the military was placed on red alert and the rebel troops were blockaded, leading them to return to barracks.[8] The following day, Aquino announced she had sacked Enrile as Defense Secretary and that she would revamp her Cabinet, "to give the government a chance to start all over again."[9]

From 27–29 January 1987, around 100 soldiers led by Colonel Oscar Canlas seized the main compound of GMA Network in Quezon City,[10] while other troops attempted in vain to capture Sangley Point Air Force Base in Cavite.[11] One rebel soldier was killed, while 35 people were injured.[12]

On Black Saturday 1987 (18 April), 13 rebel soldiers staged a raid on Fort Bonifacio. It was repelled within the morning, with one rebel soldier dead.[13]

In July 1987, a plot to stage another coup attempt through a military takeover of Manila International Airport was uncovered before it could be implemented, with four officers being court-martialled for the plot.[14]

On 28 August 1987, the most serious attempt up to then to overthrow Aquino's government was launched by members of the Reform the Armed Forces Movement led by Colonel Gregorio Honasan, who had been a former top aide of Enrile.[15] In the early morning of the 28th, rebel soldiers launched an attack on Malacañang Palace. The siege was repelled within a few hours, with several military and civilian casualties including Aquino's son, the future President Benigno Aquino III, who was wounded.[16] Honasan himself led the soldiers that seized portions of Camp Aguinaldo, including the headquarters of the Department of National Defense.[17] Rebel soldiers also seized parts of Villamor Airbase, three television stations in Manila, military camps in Pampanga and Cebu, and the airport in Legaspi City.[18] Various statements broadcast by the rebels referred to "the overindulgence in politics which now pervades in society",[19] the supposed mishandling of the communist insurgency, and the deplorable economic condition of the military rebels.[20] By day's end, government troops were able to recapture most of the rebel-held facilities, and the coup had fizzled out by the 29th. 53 were dead and more than 200 wounded;[21] many of the fatalities were unarmed civilians who were fired upon by rebels after they were jeered by the crowd.[21] Honasan himself evaded capture, while Enrile (by then a Senator), denied involvement in the coup.[21]

Following the coup attempt, the Aquino government seemingly veered to the right, dismissing perceived left-leaning officials such as Executive Secretary Joker Arroyo and tacitly authorising the establishment of armed, quasi-military groups to combat the ongoing communist insurgency.[22] It was also believed that General Fidel Ramos–who remained loyal to Aquino–emerged as the second-most-powerful person in government following his successful quelling of the coup.[23] Across-the-board wage increases for soldiers were also granted.[24] Aquino herself meanwhile sued Philippine Star columnist Louie Beltran for libel after he wrote that the President hid under her bed when the Palace was under siege.

On 1 December 1989, three rebel T-28D Trojans (Tora-Tora) raked Malacañan Palace with rockets and gunfire. The rebel soldiers wrongly assumed that they achieved air superiority by effectively neutralising the assets of the 5th Fighter Wing of the Philippine Air Force. Rebel soldiers in Mactan successfully trapped most of the F-5s and combat-ready pilots, preventing them from interfering with rebel operations. Meanwhile, at Basa Air Base, only three F-5A and an F-5B remained partial mission capability.

Squadron Commander Danilo Atienza of the 6th Tactical Fighter Squadron (Cobras) ordered his maintenance crew to expedite bringing the F-5s back to full operation. Later that same day, three F-5s under Atienza's command fought the rebel T-28s, culminating in the destruction of the Tora-Tora on the ground at Sangley Point.

The elimination of the T-28s turned the tide against the rebels, but at the cost of the F-5A flown by Atienza, who died in one of the strafing runs. Atienza was awarded the Medal of Valor for his heroism, and the airfield at Sangley Point was renamed in his memory. It is especially worth noting that, had it not been for the intervention, the Aquino government would have been overthrown.

On 4 March 1990, suspended Cagayan governor Rodolfo Aguinaldo directed his private army estimated at 300 men[25] to seize the Hotel Delfino in Cagayan's capital of Tuguegarao following his indictment on charges of rebellion and murder relating to his support for the failed Dec. 1-9, 1989 coup attempt against President Aquino. Brig. Gen. Oscar Florendo, armed forces chief of Civil Military Relations, was sent to Tuguegarao by Aquino to serve Aguinaldo with an arrest warrant.[26] After Aguinaldo's men seized control of Hotel Delfino where the general was staying, Florendo was taken hostage along with more than 50 other hotel guests. Though he was thought to have been a long-time friend of Aguinaldo's,[25] Florendo was shot at close range in the hotel and later died of his wounds.[27] Hours of standoff ensued between the two sides until nearly 1,000 government troops[25] launched an attack to dislodge Aguinaldo's forces from the hotel; government forces prevailed after more than 100 of Aguinaldo's men surrendered and about 90 were captured.[28] During this siege at least a dozen others were killed in or around the hotel; scores of civilian supporters of Aguinaldo were arrested; and a truck with assault rifles, mortars, and crates of ammunition was captured.[29] Following this melee, Aguinaldo fled with about 90 fighters for mountains in the north.[27]

The last coup attempt against President Aquino happened on 4 October 1990, when mutinying soldiers staged a dawn raid on an army base in Mindanao. The seizure lasted for two days, ending with Brigadier General Danilo Lim and 21 others capitulating to the government on 6 October.
