During the War, A. R. Pillai wrote several articles in German newspapers and gave lectures in various places in Germany, at various universities and other institutions, on Indian history, culture and architecture. Bhupendranath Datta of the India Independence Committee wrote "We want brochures on economic, political, social, religious, etc. , showing how British rule is injuring and hindering the development of the Indian people on the above-mentioned lines. Of course the books or booklets will be published in the name of the Committee ". Among them was an article in "Westermanns Monatshefte" of December 1914 which called for German support for the Indian struggle for freedom under the title "Indien Und Die Europaische Krisis" (India and the European Crisis- in translation. Some of these articles and the texts of the lectures were later brought out in book form; eight of these books are listed in the Authors' Catalogue in the Library of the University of Göttingen. One of these books is entitled Deutschland- Indiens Hoffnung (Germany – India's Hope – in translation). He also wrote and published articles on various aspects of life in Germany like Education in Germany, etc., in the then-famous Indian magazine, "The Modern Review", of Calcutta.
