American attempts to expand its territory and population ramped up in early 1865.Footnote ¹ On January 7, 1865, Waldemar Raaslöff attended a dinner hosted by the French chargé d’affaires, L. De Geoffroy, with several Washington dignitaries present including US Secretary of State William Seward. The presence of both Seward and Raaslöff was no coincidence. Authorized by President Lincoln, who had shown Raaslöff an “exceptional” amount of attention at the White House New Year’s reception five days earlier, Seward suggested that he and Raaslöff sit down before dinner in a room adjacent to the dining room to discuss a proposition that Raaslöff almost immediately thereafter relayed to the Danish Ministry of Foreign Affairs in a dispatch labeled “Confidential.”Footnote ²

Seward wanted to bring it to “the Danish government’s attention” that the United States “desired through purchase to attain possession of our West Indian Islands.”Footnote ³ The American proposition was motivated by the perceived need for a naval and coaling station in the Caribbean, and St. Thomas was at the top of empire-building Americans’ wish list.

In Raaslöff’s account, Seward had wanted to “put forward this Overture” for “quite some time” but had until now not been able to find “a suitable moment.”Footnote ⁴ The reason was an Old World conflict, now known as the Second Schleswig War, that turned out to be an important first step in Otto von Bismarck’s Grossstaatenbildung – the unification of the German states – the consequences of which had only recently become clear.Footnote ⁵

For Danish politicians, military personnel, and civilians alike, the conflict was devastating.Footnote ⁶ The war reduced Denmark’s territorial size by one-third and its population by 40 percent and thrust the country further into international Kleinstaat status – so much so that people wondered if Denmark could even survive as a nation and whether it offered economic prospects worthy of future generations’ pursuit.Footnote ⁷

At the peace conference in London, Danish delegates had, “in confidence” and ultimately unsuccessfully, suggested ceding the islands of St. Croix, St. Thomas, and St. John to Prussia and Austria in exchange for a redrawn border, but there were still raw emotions – and potential real political ramifications – associated with a sale.Footnote ⁸ The Civil War, however, had shown the need for the United States, as part of its own Grossstaatenbildung, to become a “naval power,” and, now that the peace agreement between “Denmark and the German great powers had taken effect,” Seward trusted that negotiations could be conducted with “the greatest possible delicacy and discretion.”Footnote ⁹

Still, the Schleswig question complicated American imperial pursuits. As Erik Overgaard Pedersen has shown, Denmark’s foreign policy after 1864 was primary determined by attempts to regain at least part of Schleswig and minimize any further loss of territory or population. To affect such an outcome, support from France and Great Britain – who were wary of the United States extending its strategic and military position into the Caribbean – was crucial. On the other hand, a successful sale of the Danish West Indies would bolster the depleted Danish treasury while also resolving a complicated – and by 1865 no longer economically beneficial – colonial relationship in a far-away region.Footnote ¹⁰

These intricate international relationships would, along with the American domestic tension over citizenship questions, determine the negotiations for the next five years. In the end, despite a treaty signed by both American and Danish diplomats, the United States, in Seward’s words, chose “dollars” over “dominion” as the Senate never ratified the agreement and thereby revealed the limits of small state diplomacy as Danish politicians had little, if any, leverage.Footnote ¹¹

Initially, however, it was Danish fear related to the threshold principle that hampered the negotiations.Footnote ¹² Raaslöff, for example, described the thought of losing the West Indian Islands as “too painful for me to entertain” and sensed that a sale “would be contrary” to King Christian IX’s “feelings.”Footnote ¹³ The origins of such “painful” thoughts, and Schleswig’s future importance, were found in an attempt to consolidate the Danish Kingdom more clearly along ethnic and linguistic lines.Footnote ¹⁴ On November 13, 1863, the Danish parliament passed the so-called November Constitution aiming to divide Schleswig from the mainly German-speaking Holstein.Footnote ¹⁵ This move, however, was seized upon by leading politicians within the German Federation, the Prussian minister-president Otto von Bismarck among them, as a breach of the London Treaty following the First Schleswig War. Within months, war between Denmark and Prussia – the former aided by a contingent of Swedes, Norwegians, and Finns, the latter allied with Austria – broke out.

These Old World developments were followed closely in America by politicians, diplomats, and Scandinavian immigrants alike.Footnote ¹⁶ Emigranten, Fædrelandet, and Hemlandet ran weekly updates, and in New York Scandinavian leaders and diplomats, led in part by Waldemar Raaslöff, organized a fundraising drive.Footnote ¹⁷ The war found its decisive military moments at the battles of Dybböl and Als. After a two-month-long siege, numerically superior Prussian troops overran the Danish ramparts at Dybböl on April 18, 1864, and by late June seized all of mainland Jutland. As noted, the war’s consequences were deeply felt in Northern Europe.Footnote ¹⁸ Not only had Denmark lost sizable territory and population to emerging great powers in Europe, the post-war years also saw Denmark, Sweden, and Norway lose population to emigration, in part due to Seward’s promotion of the Homestead Act.

While the Second Schleswig War for some months made it more difficult for Scandinavians to emigrate to North America, as passage between Denmark and northern Germany (e.g. Hamburg) for a period was not possible, the end of the war led a number of Scandinavian immigrants west. For Swedish, Norwegian, and Danish citizens returning home with military experience in the summer of 1864, the United States became an increasingly attractive place to resume a military career.

On September 16, 1864, American consul William W. Thomas Jr. wrote from the Kingdom of Sweden and Norway that Swedish volunteers from the war of 1864 were arriving “in squads of five, ten, and twenty” and that all heartily wished to “go to America and join the forces of the Union.”Footnote ¹⁹ Thomas personally arranged for these soldiers’ travel by raising money and working out arrangements with captains in Hamburg. While acknowledging that “as consul I can have nothing to do with enlisting soldiers,” Thomas nevertheless wrote with pride that he had “forwarded over thirty [Swedish veterans] this week” whose fare had been paid by “good friend[s] in America, including the Consul himself.”Footnote ²⁰ Thus, Thomas knowingly leveraged Swedish veterans’ post-war economic anxiety to add military manpower in opposition to the interest of Swedish authorities but claimed to provide a valuable opportunity that the veterans’ themselves sought.Footnote ²¹

Thomas’ example was far from singular. While recruitment in Germany was officially illegal, more than 1,000 men in Hamburg were enlisted through Boston-based agents in the latter years of the war, and British diplomats raised numerous complaints of “fraudulent enlistment” as well.Footnote ²²

Additionally, as described in Emigranten, the German Press reported that “several” Danish officers, some of whom may have been living south of the recently redrawn Danish-German border, were about to leave for America from Hamburg and Bremen in December 1864. According to an article in Hamburg Nachrichten (Hamburg Intelligencer), eleven war veterans had arrived in the port city and “a large number of comrades were expected to follow.”Footnote ²³

These Scandinavian war veterans were, in part, looking for opportunities to use their military experience in the American Civil War, but the Homestead Act, which had taken effect in 1863, also became an increasingly powerful pull factor. After 1864, Scandinavian immigrants, with limited opportunity for upward social mobility in the Old World, thereby played into Seward’s Homestead vision of European migration adding to the nation’s population, pool of recruits, and territory through the Confederacy’s defeat and western expansion when Old World conditions became too desperate.Footnote ²⁴

The Scandinavians who did arrive expressed pride in the nation they had now become part. “At the present time America has a great army and perhaps more than all of Europe’s armies,” wrote Norwegian-born Ole Jakobsen Berg in January 1865, adding that no country could measure up to the United States. Yet how the newly adopted nation would maintain this appeal and simultaneously reconstruct itself, with the South’s added population and territory, after four years of Civil War remained an open question. To Seward, part of the answer was continued expansion.

Despite being a small state diplomat, Raaslöff had cultivated a fruitful relationship with William Seward stretching back to at least 1861, when the two agreed to explore colonization of “now emancipated negroes” in the Caribbean.Footnote ²⁵ The mutual trust made Seward confident that he could count on Raaslöff’s “discretion” when he opened negotiations for the purchase of St. Thomas, St. Croix, and St. John on January 7, 1865, and Raaslöff on the other hand reported that Seward was “entirely serious” and acted on behalf of the president.Footnote ²⁶ According to Raslöff’s report of the meeting, Seward stated that “the United States naturally would not want to see” the islands fall into the hands of “another power” and promised the “most loyal and most friendly” negotiating position toward Denmark.Footnote ²⁷ If Seward’s proposal did indeed give “occasion for negotiations,” the American secretary of state promised that they would be conducted in the “most ‘generous,’ ‘chivalrous’ and ‘delicate’ manner.”Footnote ²⁸

The meeting sparked high-level negotiations between Seward’s Department of State and the Danish government often represented by Raaslöff. Despite the Danish king’s hesitancy, which initially put negotiations on hold, Raaslöff was notified by the Danish Ministry of Foreign Affairs on February 24, 1865, that the country’s “financial and political position” necessitated a thorough consideration of the American proposal and that “on an occasion such as this, personal feelings should not be the sole factor.”Footnote ²⁹

Yet the negotiations were derailed – as were so many other lives and policy decisions – on April 14, 1865, by John Wilkes Booth’s fateful shot in Ford’s Theater and Lewis Powell’s knife-wielding attack on Seward.Footnote ³⁰ The following day, Raaslöff received a melancholic message from Acting Secretary of State William Hunter, who had the “great misfortune” to inform him that:

Raaslöff, who responded to Hunter’s news with “deep and sincere grief,” on April 22, 1865, reported home to the Danish government that a planned meeting with the secretary of state would now be postponed indefinitely.Footnote ³²

It was soon clear that the assassination of President Lincoln, who had recently laid out a vision of reconstruction with “malice towards none” and a personal preference for Black men’s suffrage, had far-reaching consequences inside and outside American borders.Footnote ³³ Lincoln’s successor, Andrew Johnson, shared the late president’s homestead advocacy and vision of expansion into the Caribbean through purchase of “the Virgin Islands,” but in his opposition to freedpeople’s landownership and equality he helped legitimize ideas of Black inferiority and helped exacerbate splits in the Republican Party.Footnote ³⁴ Such nationwide debates over expansion and equality also rippled through Scandinavian-American communities.
