question: Which battle took place first Operation Dragoon or Battle of Guam ?
answer: Battle of Guam
context: Title: Battle of the Allia
  Passage: The Battle of the Allia was fought between the Senones (one of the Gallic tribes which had invaded northern Italy) and the Romans.  It was fought at the confluence of the rivers Tiber and Allia, eleven Roman miles (16 km) north of Rome.  The Romans were routed and subsequently the Senones sacked Rome.  The common date given for the battle is 390 BC.  This is based on the account of the battle by the Roman historian Livy and the Varronian Chronology, a Roman dating system.  The ancient Greek historian Polybius, who used a Greek dating system, derived the date 387/6 BC.  Plutarch wrote that the battle took place just after the summer solstice when the moon was near the full, a little more than three hundred and sixty years from the foundation of Rome.  That would be shortly after 393 BC.  Tacitus said that the battle took place the 15 before the Kalends of August, which is 18 July.
  Title: Battle of Middle Boggy Depot
  Passage: The Battle of Middle Boggy sometimes called either Battle of Middle Boggy River or Battle of Middle Boggy Depot, took place on February 13, 1864 in Choctaw Indian Territory, 4 miles south of what is now Allen in Pontotoc County, Oklahoma.  Advancing down the Dragoon Trail toward Fort Washita, Union Colonel William A. Phillips sent out an advance of approximately 350 men from the 14th Kansas Cavalry (led by Maj. Charles Willetts) and two howitzers (led by Captain Solomon Kaufman) to attack a Confederate outpost guarding the Trail's crossing of Middle Boggy River.  The Confederate force was led by Captain Jonathan Nail and composed of one company of the First Choctaw and Chickasaw Cavalry, a detachment of the 20th Texas Cavalry and part of the Seminole Battalion of Mounted Rifles.  The outpost was about 12 miles from Muddy Boggy Depot, which was held by the Confederates.  The "Encyclopedia of Oklahoma History and Culture" says that the battlefield was 15 miles northeast of the depot, whereas the battlefield marker says the distance was 12 miles.  The Confederate force at the outpost, consisting of 90 poorly armed men, were caught off guard when Willetts attacked them.  Outnumbered and outgunned, the Confederates held off the Union cavalry attack for approximately 30 minutes before retreating to the rest of Lt. Col. John Jumper's Seminole Battalion, who were not at the main skirmish.  The Confederates retreated 45 miles southwest down the Dragoon Trail.  The Union advance continued south toward Ft. Washita the next day, but when the expected reinforcements did not arrive Philips' Expedition into Indian Territory stalled on February 15, near old Stonewall.
  Title: Battle of Clitheroe
  Passage: The Battle of Clitheroe was a battle between a force of Scots and English knights and men at arms which took place on 10 June 1138 during the period of The Anarchy.  The battle was fought on the southern edge of the Bowland Fells, at Clitheroe, Lancashire.  It took place in the course of an invasion of England by King David I of Scotland.  In the summer of 1138, King David split his army into two forces.  One of them, commanded by William fitz Duncan, Mormaer of Moray, marched into Lancashire.  There he harried Furness and Craven.  On 10 June, William fitz Duncan was met by a force of knights and men-at-arms.  A pitched battle took place and the result was that the English army was routed.  The battle was a prelude to the Battle of the Standard later in the summer, where the result was reversed.
  Title: Battle of the Bay of Biscay
  Passage: The Battle of the Bay of Biscay was a naval action that took place on 28 December 1943 during World War II as part of the Atlantic campaign.  The battle took place in the Bay of Biscay between two light cruisers of the British Royal Navy, and a destroyer and a torpedo boat flotilla of the German Kriegsmarine hoping to intercept and escort a blockade runner.  The battle was fought as part of the Allied Operation Stonewall which was to intercept German blockade runners off the west coast of France.  In the confused action that followed the two British cruisers HMS "Enterprise" and HMS "Glasgow" respectively sank "T-26", together with her sister ship "T-25" and the destroyer "Z27".
  Title: Battle of Marseille
  Passage: The Battle of Marseille refers to the combat and other actions from August 21–28, 1944 which led to the liberation of Marseille by French forces in World War II.  The groundwork was laid by the Allied invasion of southern France in Operation Dragoon on 15 August 1944 by the United States Seventh Army, with major support from the French First Army.
  Title: Operation Dragoon
  Passage: Operation Dragoon (initially Operation Anvil) was the code name for the Allied invasion of Southern France on 15August 1944.  The operation was initially planned to be executed in conjunction with Operation Overlord, the Allied landing in the Normandy, but the lack of available resources led to a cancellation of the second landing.  By July 1944 the landing was reconsidered, as the clogged-up ports in Normandy did not have the capacity to adequately supply the Allied forces.  Concurrently, the French High Command pushed for a revival of the operation that would include large numbers of French troops.  As a result, the operation was finally approved in July to be executed in August.
  Title: Battle of Guam (1944)
  Passage: The Second Battle of Guam (21 July – 10 August 1944) was the American recapture of the Japanese-held island of Guam, a U.S. territory in the Mariana Islands captured by the Japanese from the U.S. in the 1941 First Battle of Guam during the Pacific campaign of World War II.
  Title: Operation Anaconda
  Passage: Operation Anaconda took place in early March 2002.  CIA Paramilitary Officers, working with their allies, attempted to destroy al-Qaeda and Taliban forces.  The operation took place in the Shahi-Kot Valley and Arma Mountains southeast of Zormat.  This operation was the first large-scale battle in the United States War in Afghanistan since the Battle of Tora Bora in December 2001.  This was the first operation in the Afghanistan theater to involve a large number of U.S. conventional (i.e. non-Special Operations Forces) forces participating in direct combat activities.
  Title: Siege of Sevastopol (1941–42)
  Passage: The Siege of Sevastopol also known as the Defence of Sevastopol (Russian: Оборона Севастополя , transliteration: "Oborona Sevastopolya") or simply the Battle of Sevastopol (German: Schlacht um Sewastopol) was a military battle and a siege that took place on the Eastern Front of the Second World War.  The campaign was fought by the Axis powers of Germany, Romania, and Italy against the Soviet Union for control of Sevastopol, a port in the Crimea on the Black Sea.  On 22 June 1941 the Axis invaded the Soviet Union during Operation Barbarossa.  Axis land forces reached the Crimea in the autumn of 1941 and overran most of the area.  The only objective not in Axis hands was Sevastopol.  Several attempts were made to secure the city in October and November 1941.  A major attack was planned for late November, but heavy rains delayed the Axis attack until 17 December 1941.  Under the command of Erich von Manstein, Axis forces were unable to capture Sevastopol during this first operation.  Soviet forces launched an amphibious landing on the Crimean peninsula at Kerch in December 1941 to relieve the siege and force the Axis to divert forces to defend their gains.  The operation saved Sevastopol for the time being, but the bridgehead in the eastern Crimea was eliminated in May 1942.
  Title: Battle of Kuwait International Airport
  Passage: The Battle of Kuwait International Airport occurred on February 27, 1991 during the 1st Gulf War.  It was a tank battle between the United States and Ba'athist Iraq.  Despite being a very large battle it is often overlooked compared to the other battles which took place during the war.  No less than elements of 18 divisions total participated in this battle.  U.S. Army Special Forces units and multiple Iraqi Commando units were also in theatre.  In reality the battle took place over a span of three days despite the primary battle at Kuwait International Airport lasting only one day.  Much of the combat actually took place en route to the airport.  The battle featured the "Reveille Engagement" which went on to become the biggest and fastest tank battle in United States Marine Corps' entire history.
