In 1910, Zamorski entered the Jan Matejko Academy of Fine Arts in Kraków, where he studied painting under Józef Mehoffer (he spent two years there, 1910–11, and 1917–18).

Some time in either late 1917 or early 1918, he joined Polish Military Organisation (POW), and became commandant of Kraków District.

In 1925 – 27, Zamorski was chief of Infantry Department of the Ministry of Military Affairs, and in 1928–1935, he served in the Polish General Staff.

On 25 January 1935 Zamorski was released from the Army and appointed chief of the Polish State Police.

He was appointed chief of Reserve Unit of the Polish Independent Carpathian Rifle Brigade, and retired from active service in 1941.

On 11 November 1966, Polish president-in-exile, August Zaleski, promoted Kordian Zamorski to the rank of Divisional general.
