After almost a century the US Navy has reintroduced tumblehome into the design of naval combatants. This paper discusses some of the reasons tumblehome was originally designed into ships and why it served it owners well for many centuries. The transition from sail to steam power a little over a century ago led to a variety of problems with the combatant ships designed with tumblehome where the lack of damage stability caused a major loss of life as these ships sank so quickly. During World War I ships designed with tumblehome fell out of favor and some of the ships were actually modified to remove the tumblehome from the design. These changes in the design of tumblehome ships are discussed in this paper.

In the two decades before World War I, Irving Fisher and his French contemporary Adolphe Landry presented and extended Boehm-Bawerk's theory capital and interest, although both of them criticized Boehm-Bawerk's concept of an average period of production. They analyzed each other's work on interest theory in books reviews and books. They both attempted to construct an operationally meaninful version of the quantity theory of money, with Fisher building explicitly on early studies by Landry and Pierre des Essars in France and by Edwin Kemmerer and David Kinley in the US.

Polish Issues in Canada During World War I The article presents the impact of World War I on Polish immigrants in Canada, the position of the Polish ethnic group in this country and the efforts of persons of Polish descent in regard to recruitment for the Polish Army in North America. Poles, who were subjects of Germany or the Austro-Hungarian Empire were treated as enemy aliens. Those people were forced to register and report to the police on a regular basis and some of them were interned in labour camps during the war. Some were released from the camps after an intervention of Polish organizations and priests. Soldiers of Polish descent, volunteers and recruits also fought in the Canadian Expeditionary Forces in Europe. Over 20,000 Polish volunteers from the US (including over 200 from Canada) enrolled in a training camp formed in Niagara-on-the-Lake, Ontario on the border with the US. The problems with the organization and functioning of the camp, and opinions on Polish volunteers shaped the attitude of many Canadians towards the Polish diaspora and the newly established Polish state. Keywords: World War I, Polish Diaspora in Canada, Niagara-on-the-Lake camp, Haller’s Army, Colonel Arthur D’Orr LePan Streszczenie Artykuł przedstawia kilka przykładów obrazujących oddziaływanie wydarzeń I wojny światowej na żyjących w Kanadzie polskich imigrantów, pozycję polskiej grupy etnicznej w tym kraju oraz na aktywność osób polskiego pochodzenia na rzecz rekrutacji do wojska polskiego w Ameryce Północnej. Polaków, którzy byli poddanymi Niemiec lub monarchii austro-wegierskiej traktowano jak przedstawicieli państw wrogich. Mieli obowiązek rejestracji i regularnego zgłaszania się na policję a niektórzy zostali internowani w stworzonych w czasie wojny obozach pracy. Część z nich była z tych obozów zwolniona po interwencji polskich organizacji i polskich duchownych. Żołnierze polskiego pochodzenia, zarówno ochotnicy jak i poborowi, znaleźli się także w oddziałach Kanadyjskich Sił Ekspedycyjnych walczących w Europie. Ponad 20 tys. polskich ochotników z USA (w tym ponad 200 z Kanady) zgłosiło się też do obozu szkoleniowego utworzonego w Niagara-on-the-Lake, Ontario, przy granicy z USA. Problemy z organizacją i funkcjonowaniem tego obozu oraz opinie o polskich ochotnikach, kształtowały nastawienie wielu Kanadyjczyków do polskiej grupy etnicznej i nowotworzonego Państwa Polskiego.

Chapter 1 examines how Louis Adamic used the paradox of immigrants providing the labor to make the United States the wealthiest nation on earth while receiving mostly misery in return. The xenophobes who dominated US politics after World War I made it clear that Slavs were not quite “white” and thus not quite American. Adamic and his fellow countrymen found themselves in between white and black on the US racial spectrum and trapped in between Slovenian and US cultures. During the 1920s, he grappled with this liminality by employing literary modernism and writing from the perspective of an exiled peasant. In 1933, he added a political dimension to work when writing about slovenstvo (Slovene spirit) at a crucial moment in his homeland’s history.

This chapter explores the advent of aviation in the US Marine Corps, beginning with the determination of Alfred A. Cunningham to excite the Corps’ interest in the possibilities of heavier-than-air powered flight. This is followed by an examination of the employment of Marine Corps aviation in World War I, including predeployment training and combat operations. The chapter concludes by addressing the import of this experience, especially with regard to the development of Marine Corps aviation in the small wars era.


This introduction describes the strategic bombing mission of the US Army Air Forces’ Eighth Air Force against the Fock-Wulfe plant at Bremen, Germany, on April 17, 1943, assessing the use of high-altitude daylight precision bombing,. The introduction then reviews American strategic bombing theory from its origins in World War I to the thinking of three great interwar air power theorists―the Italian Giulio Douhet, the Briton Hugh Trenchard, and the American Billy Mitchell―to the founding of the Air Corps Tactical School (ACTS), the development of the Norden bombsight and B-17 bomber, and the genesis of HADPB theory at the Air Corps Tactical School.

The enormous loss of life and physical destruction caused by the First World War led people to hope that there would never be another such catastrophe. How then did it come about that there was a Second World War causing twice the 30 million deaths and many times more destruction as had been caused in the previous conflict? The ‘Introduction’ poses several questions: why did this war start so soon after World War I? Why was it considered a world war and not just European? What triggered the involvement of various nations? How did the Allies win? These questions are considered in subsequent chapters.

The history of Muslims in America dates back to the transatlantic mercantile interactions between Europe, Africa, and the Americas. Upon its arrival, Islam became entrenched in American discourses on race and civilization because literate and noble African Muslims, brought to America as slaves, had problematized popular stereotypes of Muslims and black Africans. Furthermore, these enslaved Muslims had to re-evaluate and reconfigure their beliefs and practices to form new communal relations and to make sense of their lives in America. At the turn of the 20th century, as Muslim immigrants began arriving in the United States from the Middle East, Eastern Europe, and South Asia, they had to establish themselves in an America in which the white race, Protestantism, and progress were conflated to define a triumphalist American national identity, one that allowed varying levels of inclusion for Muslims based on their ethnic, racial, and national backgrounds. The enormous bloodshed and destruction experienced during World War I ushered in a crisis of confidence in the ideals of the European Enlightenment, as well as in white, Protestant nationalism. It opened up avenues for alternative expressions of progress, which allowed Muslims, along with other nonwhite, non-Christian communities, to engage in political and social organization. Among these organizations were a number of black religious movements that used Islamic beliefs, rites, and symbols to define a black Muslim national identity. World War II further shifted America, away from the religious competition that had earlier defined the nation’s identity and toward a “civil religion” of American democratic values and political institutions. Although this inclusive rhetoric was received differently along racial and ethnic lines, there was an overall appeal for greater visibility for Muslims in America. After World War II, increased commercial and diplomatic relations between the United States and Muslim-majority countries put American Muslims in a position, not only to relate Islam and America in their own lives but also to mediate between the varying interests of Muslim-majority countries and the United States. Following the civil rights legislation of the 1950s and 1960s and the passage of the Immigration Act of 1965, Muslim activists, many of whom had been politicized by anticolonial movements abroad, established new Islamic institutions. Eventually, a window was opened between the US government and American Muslim activists, who found a common enemy in communism following the Soviet occupation of Afghanistan in the 1980s. Since the late 1960s, the number of Muslims in the United States has grown significantly. Today, Muslims are estimated to constitute a little more than 1 percent of the US population. However, with the fall of the Soviet Union and the rise of the United States as the sole superpower in the world, the United States has come into military conflict with Muslim-majority countries and has been the target of attacks by militant Muslim organizations. This has led to the cultivation of the binaries of “Islam and the West” and of “good” Islam and “bad” Islam, which have contributed to the racialization of American Muslims. It has also interpolated them into a reality external to their history and lived experiences as Muslims and Americans.

This historical review explores Harvey Cushing's difficulties with both the British and American armies during his World War I service to definitively examine the rumor of his possible court martial. It also provides a further understanding of Cushing the man. While in France during World War I, Cushing was initially assigned to British hospital units. This service began in May 1917 and ended abruptly in May 1918 when the British cashiered him for repeated censorship violations. Returning to American command, he feared court martial. The army file on this matter (retrieved from the United States National Archives) indicates that US Army authorities recommended that Cushing be reprimanded and returned to the US for his violations. The army carried out neither recommendation, and no evidence exists that a court martial was considered. Cushing's army career and possible future academic life were protected by the actions of his surgical peers and Merritte Ireland, Chief Surgeon of the US Army in France. After this censorship episode, Cushing was made a neurosurgical consultant but was also sternly warned that further rule violations would not be tolerated by the US Army. Thereafter, despite the onset of a severe peripheral neuropathy, probably Guillian Barré's syndrome, Cushing was indefatigable in ministering to neurosurgical needs in the US sector in France. Cushing's repeated defying of censorship regulations reveals poor judgment plus an initial inability to be a “team player.” The explanations he offered for his censorship violations showed an ability to bend the truth. Cushing's war journal is unclear as to exactly what transpired between him and the British and US armies. It also shows no recognition of the help he received from others who were instrumental in preventing his ignominious removal from service in France. Had that happened, his academic future and ability to train future neurosurgical leaders may have been seriously threatened. Cushing's foibles notwithstanding, all realized that he contributed greatly to both British and US war neurosurgery. United States Army surgeons who operated upon brain wounds in France recognized Cushing as their leader.
