Between 1920 and 1939, Vilnius, the constitutional capital of Lithuania, was annexed by Poland, prompting the Lithuanian government and civil life to relocate to Kaunas, the temporary capital. Despite local tensions, both cities faced a shared geopolitical predicament in the 1930s, being between ‘Scylla and Charybdis’. Nazi Germany to the west and Bolshevik Russia to the east sought to revise the existing order, threatening Poland and the Baltic region respectively. Anticipating military attacks, both the Lithuanian and Polish governments began preparing in the early 1930s. Archival data reveal that the military, academic specialists and civilians underwent paramilitary training to address threats, such as gas and air attacks, and to develop crisis management strategies. Medical professionals played a critical role in devising measures to prevent and treat injuries from chemical warfare, leveraging medical expertise to mitigate potential losses. This article aims to examine and compare the medical and civilian preparedness for chemical attacks in Vilnius and Kaunas. Our research focuses on two objectives: analysing primary archival documents to uncover strategies by government bodies, military doctors, the Polish Red Cross, and related organisations; and reviewing the public press to understand societal perceptions of the looming military threat.
