Question: Operation Falcon Summit was led in a battle fought when?

Context paragraphs:
Operation Falcon (USFWS operation): Operation Falcon was an undercover operation conducted by the US Fish and Wildlife Service (USFWS) and the Canadian Wildlife Service from 1982–1984.  The investigation into the illegal sale of federally protected birds resulted in 63 people being tried or taking a plea bargain.  Of the cases that went to trial, there were 5 acquittals, 5 felony convictions, 44 misdemeanor convictions and 1 civil conviction.  Jeff McPartlin, a falconer who was reported to be integral to the operation, received the Monitor award for his work.  He was later ejected from the North American Falconers Association because officials from the group felt "the man had deceived people".  Many falconers were upset at the tactics used during the investigation and felt that the sting inappropriately targeted bystanders rather than professional long term smugglers.  Additional information, much published by the National Falconry organization, is available in the following link: http://resourceclearinghouse.blogspot.com/2010/04/operation-falcon.html

Battle of Pima Butte: The Battle of Pima Butte, or the Battle of Maricopa Wells, was fought on September 1, 1857 at Pima Butte, Arizona near Maricopa Wells in the Sierra Estrella.  Yuma, Mohave, Apache and Yavapai warriors attacked a Maricopa village named Secate in one of the largest battles in Arizona's history.

Battle of Chunuk Bair: The Battle of Chunuk Bair (Turkish: Conk Bayırı Muharebesi ) was a World War I battle fought between the Ottoman defenders and troops of the British Empire.  British units that reached the summit of Chunuk Bair early on 8 August 1915 to engage the Turks were the Wellington Battalion of the New Zealand and Australian Division, 7th Battalion, Gloucestershire Regiment and 8th Battalion, Welch Regiment of the 13th (Western) Division.  The troops were reinforced in the afternoon by two squads of the Auckland Mounted Rifles Regiment, New Zealand and Australian Division.  The first troops on summit were severely depleted by Ottoman return fire and were relieved at 10:30 pm on 8 August by the Otago Battalion (NZ), and the Wellington Mounted Rifles Regiment New Zealand and Australian Division.  The New Zealand troops were relieved by 8:00 pm on 9 August by the 6th Battalion, Loyal North Lancashire Regiment and 5th Battalion, Wiltshire Regiment, who were massacred and driven off the summit in the early morning of 10 August, by an Ottoman counter-attack led by Mustafa Kemal.  The capture of Chunuk Bair, (Turkish: "Çanak Bayır" Basin Slope, now "Conk Bayırı"), the secondary peak of the Sari Bair range, was one of the two objectives of the Battle of Sari Bair, the British August Offensive at Anzac Cove and Suvla, to try to break the stalemate that the campaign had become.  The capture of Chunuk Bair was the only success for the Allies of the campaign but it was fleeting as the position proved untenable.  The Ottomans recaptured the peak for good a few days later.

Battle of Byeokjegwan: The Battle of Byeokjegwan (or Pyŏkje) (Chinese: 碧蹄館大戰; "Bì tí guǎn dàzhàn") was a battle fought on January 27, 1593 (January 26 according to the Japanese calendar of the time), between the armies of the Ming Dynasty led by Li Rusong, and the Japanese forces under Tachibana Muneshige, Ukita Hideie, and Kobayakawa Takakage.

Operation Medusa: Operation Medusa (September 2–17, 2006) was a Canadian-led offensive during the second Battle of Panjwaii of the war in Afghanistan.  The operation was fought primarily by the 1st Battalion, The Royal Canadian Regiment Battle Group and other elements of the International Security Assistance Force, supported by the Afghan National Army and a team from the United States 1st Battalion, 3rd Special Forces Group (Airborne) augmented by United States A Company 2nd Battalion, 4th Infantry Regiment.  Its goal was to establish government control over an area of Kandahar Province centered in the district of Panjwayi some 30 km west of Kandahar city.  A tactical victory, it resulted in the deaths of 12 Canadian soldiers; five during the major combat operations, five in bombings, and two in a mortar/RPG attack during the reconstruction phase of the operation.  Fourteen British military personnel were also killed when their plane crashed.  Despite suffering a brutal battlefield defeat, the Taliban retained their presence in Kandahar province and did not lose their will to fight, leading to the subsequent Operation Falcon Summit.  Nonetheless, Operation Medusa was at the time the most significant land battle ever undertaken by NATO.

It has been characterized as the "dying echo of the old era – for the last time in the history of naval warfare, ships of the line of a beaten fleet surrendered on the high seas".

Several of the suspects committed suicide.  It was the follow-up to the U.S. FBI operation Operation Falcon.
