This monograph offers a fresh viewpoint on the postal history of one of the most devastating sieges in modern military history, when the town of Przemyśl in the Polish province of Galicia in the Austro-Hungarian Empire was besieged by the Russian Army during the winter of 1914-1915. Establishing a provisional airmail service by the Austrian Air Force in Przemyśl marked a historic moment, as it was the first time civilian mail-laden airplanes took off and landed in a besieged fortress. This initiative was not motivated by philatelic interests but was crucial for maintaining communication between the defenders and the outside world. These events unfolded in a remote region of Eastern Europe during the early stages of World War I, shortly after the launch of the world’s first airmail service in Allahabad, India, in 1911. Although the philatelic community recognizes the significance of the Przemyśl Siege mail, it has not achieved the same prominence as the Siege of Paris (1870-1871). Nonetheless, it constitutes an essential component of aerophilately, offering ample research opportunities for postal historians and shedding light on the operation of the world’s first humanitarian airmail bridge, while preserving human stories captured in vintage cards and covers for over a century.

Keith Tranmer (1928-2018), a prominent British authority on the Przemyśl Siege, wrote: “There are many interpretations of what constitutes postal history but in my long experience that human aspect that the student can discover is the true reward of collecting, and in a subject such as the siege of Przemyśl, which has a defined beginning and end, the collector is able to relate closely to some of the personalities engaged.” This monograph explores a group of individuals I have come to "know" through their messages on flimsy cards sent by air from the besieged fortress over a century ago. I trust the senders and recipients do not mind my intrusion into their private exchanges as I seek to shed light on the intricacies of wartime postal operations. The philatelic aspects offer a glimpse into the unique circumstances that reflect the challenging conditions under which these messages were crafted. These fragile, aged cards often tell remarkable stories of human resilience.

The Przemyśl Siege during the early stages of the Great War highlights the operational effectiveness of the Imperial and Royal Air Force, as well as the military and civilian Feldpost services. Although it was a brief and irregular operation, "Fliegerpost Przemyśl" symbolized resilience and facilitated family communication. Additionally, it was used to bolster troops' morale for war propaganda purposes. Ultimately, "Fliegerpost Przemyśl" was instrumental in establishing the world's first regular and international civilian airmail service, also Austro-Hungarian, along the Vienna - Kraków - Lwów - Kyiv route by the conclusion of World War I in 1918.

Many different cards and balloon mail covers are shown in color. There is an extensive bibliography, and 4 appendices showing forerunner air cachets on unofficial mail, airmail cachets & camouflage markings on official mail, official censor marks on flown mail & cachets on paper balloon flown mail from Przemysl. This is an excellent book on a little known aspect of aerophilately.
