(詳細はKrag–Jørgensen rifle is a Norwegian-designed bolt-action rifle that was adopted in 1892 as the standard United States Army military longarm, chambered in U.S. caliber .30-40 Krag. All versions and variants were manufactured under license by the Springfield Armory between 1892 and 1903 and famously served as the longarm during the Spanish–American War. Although Krags were popular, unique and efficient, the side loading gate mechanism was slow and cumbersome to reload in combat compared to the clip loaded Spanish Mausers the Krag was up against. Thus, the U.S. Krag was replaced beginning in 1903 with the introduction of the M1903 Springfield rifle, which was essentially a copy of a Mauser, although some design elements of the Krag design remained, such as the cocking piece and famously smooth Krag bolt action. American Krags are the most plentiful and affordable of all three Krag variants, although many are sporterized, and they remain popular with collectors today. ==History== Like many other armed forces, the U.S. Army searched for a new rifle in the early 1890s to replace their old Springfield Model 1873 "trapdoor" single-shot rifles. A competition was held in 1892, comparing rifle designs from Lee, Krag–Jørgensen, Mannlicher, Mauser, Schmidt–Rubin, and about 40 other military and civilian designs. The trials were held at Governors Island, New York. Despite protests from domestic inventors and arms manufacturers—two designers, Russell and Livermore, even sued the U.S. government over the choice—the Krag–Jørgensen design was chosen by the board of officers. Approximately 500,000 "Krags" were produced at the Springfield Armory in Massachusetts from 1894 to 1904. It was the U.S. Army's primary rifle from 1894 to 1903 (when it was replaced by the M1903 Springfield rifle with its ballistically similar .30-03 cartridge), and found use in the Spanish–American War and the Philippine–American War. In this later war the rifle was referred to in a song popular with U.S. troops, a parody of "Tramp! Tramp! Tramp!", with a verse running:
According to contemporary, perhaps sensationalized accounts, the Krag's complex design was outclassed〔Stans, Samhope, ("The Krag-Jørgensen Gun: It Is Inferior In Many Respects to the Mauser Used by the Spaniards" ), ''The New York Times'', 1 August 1898〕 by the 7mm 1893 Spanish Mauser during the Spanish–American War, and proved ill-suited for use in tropical locales such as Cuba and the Philippines. American soldiers found themselves unable to match the volume of fire displayed by the Spanish 1893 Mauser rifle, with its internal box magazine that could be quickly and fully reloaded with five-round stripper clips, and a high-velocity, flat-shooting 7mm cartridge which was quickly dubbed the "Spanish Hornet". During the American assault on the strategic Cuban city of Santiago, a small force of 750 Spanish troops armed with Model 1893 Mauser rifles defended positions on San Juan and Kettle hills. The attacking force consisted of approximately 6,600 American soldiers, most of them regulars, armed with the then-new smokeless-powder Krag–Jørgensen rifle and supported by artillery and Gatling gun fire. Though the assault was successful, the Americans soon realized that they had suffered more than 1,400 casualties in the assault. A U.S board of investigation pinned the blame on the superior firepower of the Spanish Model 1893 Mauser rifles, although modern analysis has determined that many of the casualties were due to superior Spanish fortifications on the high ground. With the Krag's replacement with the Mauser-derived M1903, the rifle is tied for the shortest service life of any standard-issue firearm in US military history (1892–1903). The Krag was completely phased out of service in the Regular Army by 1907, as M1903 Springfields became available, however, the Krag was issued for many more years with the National Guard and the Army Reserve, including service in World War I with rear-echelon U.S. troops in France and as training arms at various Stateside bases. Later, many were issued to veterans' organizations such as the American Legion and the Veterans of Foreign Wars for use in military ceremonies. Still, others were sold to civilians through the Civilian Marksmanship Program and American Krag rifles are a popular and common military surplus collectible. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Springfield Model 1892–99」の詳細全文を読む スポンサード リンク
