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

<P0-S0> Operation Falcon Summit (Pashto: "Baaz Tsuka") was a Canadian-led operation in the Battle of Panjwaii and, on a larger scale, in the 2001–present War in Afghanistan. <SEP> <P1-S0> 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. <P1-S1>  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. <P1-S2>  The troops were reinforced in the afternoon by two squads of the Auckland Mounted Rifles Regiment, New Zealand and Australian Division. <P1-S3>  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. <P1-S4>  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. <P1-S5>  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. <P1-S6>  The capture of Chunuk Bair was the only success for the Allies of the campaign but it was fleeting as the position proved untenable. <P1-S7>  The Ottomans recaptured the peak for good a few days later. <SEP> <P2-S0> The Battle of Panjwaii was fought in mid-2006 between primarily Canadian and Afghan soldiers, supported by small elements of Dutch, American, and British forces, and the Taliban. <P2-S1>  There were two separate times in which the forces were involved in heavy fighting in the region. <P2-S2>  The first phase was fought in July 2006, and the second encounter lasted from September to October 2006. <SEP> <P3-S0> Operation Medusa (September 2–17, 2006) was a Canadian-led offensive during the second Battle of Panjwaii of the war in Afghanistan. <P3-S1>  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. <P3-S2>  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. <P3-S3>  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. <P3-S4>  Fourteen British military personnel were also killed when their plane crashed. <P3-S5>  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. <P3-S6>  Nonetheless, Operation Medusa was at the time the most significant land battle ever undertaken by NATO.
