The historiography of the Gallipoli campaign suggests that the Turks were critically short of ammunition for the Dardanelles coastal defences in March 1915. This theme, established by Winston Churchill, became the basis for a widespread belief that the Royal Navy, after its failure to carry the Dardanelles on 18 March 1915, simply needed one more determined naval push to breakthrough the narrows. The presumed consequence was that the Ottoman Empire, with Constantinople under the guns of the Royal Navy, would have withdrawn from the war. Using modern Turkish sources, the author examines the available quantities, placement, and expenditure of ammunition, and challenges the premise that the Turks were desperately short of heavy shells. The author concludes that the Turks had sufficient remaining ammunition to fiercely contest control of the straits.  相似文献

This article examines the Ottoman military's escalatory response to violence and frames the Armenian insurrection of 1915 in the historical context of contemporary early twentieth-century counterinsurgency campaigns. A case study is presented, from a military historian's perspective, of counterinsurgency operations conducted by the Ottoman Army's 41st Infantry Division against Armenian insurgents on Musa Da? (Musa Dagh) in an operational area south of Iskenderun (Alexandretta). In this particular operational area, it appears that the modern label which most closely approximates what happened there is ethnic cleansing. Finally, the article concludes with an objective assessment of the effectiveness of the Ottoman Army's counterinsurgency operations.  相似文献

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

The insurgency in southern Thailand has proven to be intractable over the last few years. The insurgents, who comprise several different groups, have largely retained the initiative in a series of relatively unsophisticated operations. Although involving ethnic Malay Muslims – and marked by an increasingly strong Islamist ideology – the insurgency has been predominantly ethnic rather than religious. External jihadist involvement has been minimal at best. The recent coup in Thailand may improve the odds of reaching some form of accommodation with the southern insurgents; but it is likely that the south will remain a continuing security problem for Bangkok.  相似文献
