At the end of the war, he also began working on frescoes, glass art, and mosaic art. In 1942, he exhibited works at the Venice Biennale and at the Mostra degli artisti in armi ("Artists in arms") exhibit at the Palazzo delle Esposizioni in Rome, where he presented three watercolours and seven pen drawings, all having a war theme. By this time, he was a sergeant for the Genio Ferrovieri. His first personal exhibition occurred in 1943 and was presented by Raffaello Giolli at the Galleria La Rotonda in Bergamo. He dedicated himself to teaching and the creation of works of sacred art in 1945.

 Passage 2:In 1836 de Soysa bid for the Diyatalawa kanda 'Kings Garden-Rajmal Uyana' in Hanguranketa (against British planters such as George Bird) at the request of the administrative officer of the region that had been appointed by king Sri Vikrama Rajasinha. This was an overgrown coffee (flower) estate previously used by the Kandyan kings as a country retreat. He also purchased many of the cinnamon estates that were previously owned by the Dutch administration in Moratuwa, Ratmalana, Dambuwa and Katunayake, citronella plantations in Ahangama and coconut plantatins throughout the island. His land holdings in Colombo consisted of several estates that stretched between Galle Face and Panadura. The De Soysa and Peiris family established the first Ceylonese-owned bank, the Bank of Kandy at Dalada weediya and Pettah, Colombo in 1839 & 1860, becoming the largest native commercial enterprise of the era at a time when European owned banks were reluctant to extend credit to the Ceylonese and the high interest rates of the Nattukkottai Chettiars. De Soysa was also reputed for his treatment of employees and had relied to a greater extent on the low country population. He played a significant role in improving agriculture and the infrastructure in the Kandyan province and the coastal districts.
