Relations between Serbia and the United States of America during World War I, the “Great War,” were as friendly allies. July 28, 1918, however, was especially important for Serbs and Americans. On this day America marked the fourth anniversary of the beginning of the Great War, when, according to the words of U.S. Secretary of State Robert Lansing, “honorable Serbian people were forced to defend their country and their homes against an enemy who wanted to destroy them,” and when the Serbian people, “sacrificed everything for freedom and independence.”
Americans clearly expressed their support and sympathy for the Serbian people from the very beginning of the Great War. During 1914, 1915 and 1916, enormous financial support and thousands of tons of humanitarian aid were provided to the Serbian people from the United States. There was money for food for civilians, for refugees, to fight typhoid, seed to plant for the next harvest, agricultural tools, and even funding to lease refugee transport ships.

The United States of America officially celebrated July 28, 1918 as “Serbia Day.” On July 27, U.S. Secretary of State Robert Lansing called on every American citizen to, “gather on Sunday, July 28 in their churches in order to express their sympathies toward this enslaved nation (Serbia) and their oppressed brothers in other countries and to invoke the blessing of the almighty God for them and cause that they are fighting for.” Thanks to a report by the Serbian Ambassador to the United States and an article published in Detroit News, we know today that, “over the White House and other public institutions waved the Serbian flag for the first time.” Other than the American and Serbian flags, only one other has been flown over the White House. That was the French flag, on the 131th anniversary of the fall of the Bastille, on July 14, 1920.

Second U.S. Assistant Secretary of State William Phillips and Ljubomir Mihailovic, Serbian Ambassador to the U.S. in 1918
June 1st, 1918
“Dear Mr Phillips,July 28th, 1918 is the day when the Central Powers declared war on the civilized world. That very day Austria – Hungary attacked small Serbia, because she did not agree to forfeit her independence. This attack inaugurated German – Magyar aims to subjugate the small nationalities and to effect with the tombs of these peoples a plan for the domination of the world. Serbia and the Yugoslavs had first to be crushed. And yet, brutal force did not succeed to destroy the revolutionary spirit of the Yugoslavs and of the other Slavs in Austria – Hungary.”

Twenty-sixth U.S. President Theodore Roosevelt and Ljubomir Mihailovic, Serbian Ambassador to the U.S. in 1918
July 11th, 1918
“Therefore July 28th is the most important date in this war. Nor is it important only because it marks the beginning of the war. It possesses an infinitely greater importance because the crucial question to be determined by the war is the dealing of the world with the dual empire of Austro-Hungary. The independence and the enlargement of the great Jugo-Slav state is vital to the future peace of the world; and so also the independence (not nominal, but real) of the Polish commonwealth, and of the Czecho-Slovak commonwealth…”

“Your telegram sent on July 28 has met with a very heartning [sic] response in my own heart and I am sure it will meet with an equally warm response in the hearts of everybody in the United States. We know the deep waters of suffering through which Serbia has passed and our sympathies not only, but our profound friendship and an eager desire to help, follows your courageous people throughout every stage of the present tragic course of the war. I am sure that justice to Serbia stands at the very top of any program of justice in the thoughts of every thinking and patriotic man in the United States. Please accept my warm personal greetings.

Serbian Ambassador Mihailovic’s telegram to the Serbian Government in Corfu
June 25th, 1918
“Through a friend employed in the U.S. Ministry of Foreign Affairs, I made a proposal to make, on the 28th of July – the day when Austria – Hungary declared war on Serbia, a manifestation regarding the first day of the war when the two principles started to fight – the first one being the principle of violently governing other nations and the other one being a principle of freedom for all nations. Austria as a representative of the first principle and Serbia as a defender of the second were the first countries that started to fight. Serbia sacrificed everything in that fight. This manifestation, organized by allies, would clearly mark their goal and would have enormous influence on the enslaved nations.”

Serbian Ambassador Mihailovic’s telegram to the Serbian Ministry of Foreign Affairs about U.S. Secretary of State Lansing’s appeal
July 29th, 1918
(dated July 16th, as Serbia was using the Julian Calendar at the time)
Secretary of State Lansing proposed that all churches in the United States celebrate Serbia Day, saying, “Sunday, the 28th of this month, will be exactly four years since the day when heroic Serbia refused to obey to humiliating Austro-Hungarian demands which led to the declaration of war that made Serbia defend its territory and [the] homes of its citizens. Serbs nobly responded to their duty and resisted the attacks of a country which was ten times bigger than Serbia. They managed to resist Austrians three times and only when Germany and Bulgaria helped Austria, were they forced to retreat to Albania.

There was the Serbian flag floating over the President’s House in the United States of America. What did it mean?… the meaning of the Serbian flag up there beside the Stars and Stripes …is the meaning of the alliance within our borders of the three and thirty alien groups who are helping us win Democracy for their brothers overseas.

U.S. Secretary of State Lansing’s appeal
“It is fitting that the people of the United States, dedicated to the self-evident truth that it is the right of the people of all nations, small as well as great, to live their own lives and choose their own Government, and remembering that the principles for which Serbia has so nobly fought and suffered are those for which United States is fighting, should on the occasion of this anniversary manifest in an appropriate manner their warm sympathy with this oppressed people who have so heroically resisted the aims of the Germanic nations to master the world.”

“Serbia Day Observed”
“Serbia,” said Mr. Georgevitch, “was the first State attacked in the prosecution of the German plans for world conquest. Three times the enemy succeeded in entering Serbia and three times bitterly repented it, and it was only when Austria obtained the help of Germany and Bulgaria that the Serbian army was forced across into the Albanian wilderness where it was reorganized by France to fight on the Salonica front to the end. Mr. Georgevitch expressed appreciation and thanks on behalf of Serbia for the great assistance of the United States since the beginning of the war and for our friendship.”
