In 1919, Poland purchased real estate in the environs of Gdańsk. The uncertain political future of the city at that time was conducive to the mainly German owners to start a process of selling it off. This process was taken advantage of by people associated with Mieczysław Jałowiecki, who were working to increase Polish ownership of the city. In this way, real estate was acquired on Westerplatte, where as time went by, the Polish Military Transit Depot was established.
The main person involved in purchasing real estate by Poland was Mieczysław Jałowiecki, the general delegate of the Ministry of Provisioning for the city of Gdańsk. However, he quickly found helpers with whom he cooperated during his stay in the city. They operated as part of the American Food Mission, which was related to an agreement between the Polish government and the United States on the delivery of food products from the USA through the port of Gdańsk into the interior of the country.
Witold Wankowicz (1888–1948)
Together with Jałowiecki, a delegation of several people arrived in Gdańsk. Among them was, among others, Witold Wańkowicz, a cousin of Jałowiecki's first wife and brother of the writer Melchior. Before the outbreak of World War I, he was an active football player and one of the co-founders of Wisła Kraków. He was Jałowiecki's deputy. He performed his duties with extreme conscientiousness, as evidenced by, among other things, the opinion of the general delegate himself: "I often later, in various difficult moments, thanked Providence for giving me such a unique man as my deputy."
Jałowiecki trusted him completely. Wańkowicz took an active part in the purchase of real estate on Westerplatte. He participated in the meetings of the commission discussing the acquisition of specific properties in Gdańsk. After finishing his service in Gdańsk, he served as chargé d'affaires for the Polish Embassy in the United States. As an example of his work, he organized the Polish pavilion at the World Fair in New York in 1939.
