Question: What campaign was launched by "Bomber" Harris?

Operation "Linebacker II" was a US Seventh Air Force and US Navy Task Force 77 aerial bombing campaign, conducted against targets in the Democratic Republic of Vietnam (North Vietnam) during the final period of US involvement in the Vietnam War.  The operation was conducted from 18 to 29 December 1972, leading to several informal names such as "The December Raids" and "The Christmas Bombings".  Unlike the Operation Rolling Thunder and Operation Linebacker interdiction operations, "Linebacker II" was to be a "maximum effort" bombing campaign to "destroy major target complexes in the Hanoi and Haiphong areas, which could only be accomplished by B-52s".  It saw the largest heavy bomber strikes launched by the US Air Force since the end of World War II.  "Linebacker II" was a modified extension of the Operation Linebacker bombings conducted from May to October, when the emphasis of the new campaign shifted to attacks by B-52s rather than smaller tactical fighter aircraft. <SEP>  In 1942, the British Cabinet agreed to the "area bombing" of German cities.  Harris was tasked with implementing Churchill's policy and supported the development of tactics and technology to perform the task more effectively.  Harris assisted British Chief of the Air Staff Marshal of the Royal Air Force Charles Portal in carrying out the United Kingdom's most devastating attacks against the German infrastructure and population, including the Bombing of Dresden. Marshal of the Royal Air Force Sir Arthur Travers Harris, 1st Baronet, {'1': ", '2': ", '3': ", '4': "} (13 April 1892 – 5 April 1984), commonly known as "Bomber" Harris by the press and often within the RAF as "Butcher" Harris, was Air Officer Commanding-in-Chief (AOC-in-C) RAF Bomber Command during the height of the Anglo-American strategic bombing campaign against Nazi Germany in the Second World War. <SEP>  Not limited solely to Berlin, the campaign targeted other German cities as well, to prevent the concentration of defences in Berlin.  The campaign was launched by Air Chief Marshal Sir Arthur Harris, AOC of RAF Bomber Command in November 1943.  Harris believed this could be the blow that broke German resistance: "We can wreck Berlin from end to end if the USAAF come in with us.  It will cost us between 400 and 500 aircraft.  It will cost Germany the war". The Battle of Berlin was the British bombing campaign on Berlin from November 1943 to March 1944.  By this time he could deploy over 800 long-range bombers on any given night, equipped with new and more sophisticated navigational devices such as H2S radar.  Between November 1943 and March 1944, Bomber Command made 16 massed attacks on Berlin.  The USAAF, having recently suffered heavy losses in its attacks on Schweinfurt from which it was still recovering, was unable to participate. <SEP> From February 20–25, 1944, as part of the European strategic bombing campaign, the United States Strategic Air Forces (USSTAF) launched Operation Argument, a series of missions against Nazi Germany that became known as Big Week.  The planners intended to lure the Luftwaffe into a decisive battle by launching massive attacks on the German aircraft industry.  By defeating the Luftwaffe, the Allies would achieve air superiority and the invasion of continental Europe could proceed.  The daylight bombing campaign was also supported by RAF Bomber Command, operating against the same targets at night.  Arthur Harris resisted contributing RAF forces as it diverted them from the British area bombing offensive.  It took a direct order from Air Chief Marshal Sir Charles Portal, Chief of the Air Staff, to force Harris to comply.  RAF Fighter Command also provided escort for USAAF bomber formations, just at the time that the Eighth Air Force had started introducing the P-51 long-range fighter to take over the role.  This major offensive overlapped the German Operation Steinbock, the "baby blitz" against the United Kingdom, which itself lasted from January through May 1944.
