The Ulm Campaign helped the Germans develop what plan behind the German invasion of France and Belgium in 1914?
Ulm Campaign The Ulm Campaign was a series of French and Bavarian military maneuvers and battles to outflank and capture an Austrian army in 1805 during the War of the Third Coalition. It took place in the vicinity of and inside the Swabian (then Bavarian) city of Ulm. The French Grande Armée, led by Napoleon Bonaparte, comprised 210,000 troops organized into seven corps, and hoped to knock out the Austrian army in the Danube before Russian reinforcements could arrive. Through rapid marching, Napoleon conducted a large wheeling maneuver that captured an Austrian army of 23,000 under General Mack on 20 October at Ulm, bringing the total number of Austrian prisoners in the campaign to 60,000. The campaign is generally regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century.
Operation Bolero Operation Bolero was the commonly used reference for the code name of the United States military troop buildup in the United Kingdom during World War II in preparation for the initial cross-channel invasion plan known as Operation Roundup, to be implemented in mid-1943, or for its lesser contingency alternative, Operation Sledgehammer, to be executed in the fall of 1942 in the event of German setbacks or to ease Axis pressure on the Eastern Front. ("Bolero" was the code name used in official communications to stand in for "United Kingdom" when describing the theater or movements.) What later became the Bolero plan – the buildup of a strategic air force in Great Britain in preparation for Roundup – was first submitted by Commanding General of the U.S. Army Air Forces, Henry H. Arnold, to General George Marshall, the U.S. Army Chief of Staff, on April 12, 1942, and set in motion a huge movement of men and material that laid the groundwork for Operation Overlord.
