Kadanchik was born on 12 September 1906 in the village of Moiseyevichi in Minsk Governorate to a peasant family. He graduated from primary school and was drafted into the Red Army in 1928. In 1932, Kadanchik graduated from the Kiev United Training Courses for Red Army commanders. He fought in the Soviet invasion of Poland in September 1939 and the Winter War with Finland the following year. Kadanchik joined the Communist Party of the Soviet Union in 1940.
World War II
Following the German invasion of the Soviet Union, Kadanchik fought in combat from 22 June 1941. He fought on the Southern Front, Southwestern Front, Transcaucasian Front and North Caucasian Front. On 13 December 1942, Kadanchik was appointed commander of the 1339th Rifle Regiment of the 318th Rifle Division. On 24 April 1943, he was awarded the Order of the Red Banner. During the Novorossiysk Amphibious Operation in September 1943, the regiment was to capture the area from the eastern breakwater to Staropassazhirskoy and advance to the outskirts of Mefodiyevsky. The landing began on 9 September. Before reaching the shore, Kadanchik's boat sank after it hit a mine. He was rescued by a ship returning to Gelendzhik. Kadanchik arrived on the beachhead before the evening. Lieutenant General Ivan Petrov, commander of the North Caucasian Front, concluded that a breakthrough in the German line would be most likely to succeed in the sector assigned to Kadanchik's regiment. During the second half of 10 September the Germans brought up reinforcements, launching seven counterattacks. These were repulsed but by the evening some elements of the regiment had been pushed back to the sea. During the night German attacks forced the regiment back to the coast and it became surrounded. Kadanchik was killed on 15 September when a German shell hit the bell tower from where he was observing the fighting. On 18 September, for actions during the Novorossiysk operation Kadanchik was awarded the title Hero of the Soviet Union and the Order of Lenin. He was buried in Gelendzhik and was reburied in a mass grave in the Heroes Square of Novorossiysk.
