An officer's son born in Hrtkovci, Srem (then Habsburg monarchy, now Serbia), Martin Dedovich received his training in the Engineering Academy of the Austrian Imperial-Royal Army, which he entered as a cadet at the age of 20.
In the Austro-Turkish War of 1788, which came in the wake of Koča's rebellion, Dedovich was promoted to the rank of first lieutenant and in the same year, during the siege of Bosanski Novi, he was put in charge of the opening of the 1st, 2nd, and 3rd parallel, the latter only 4 steps away from the covered road.
In the enemy cannonade on this side of the post at Pont-sur-Sambre (3 November), Dedovich distinguished himself again and was then drawn to the Battle of Tournay, the blockade of Luxembourg, and in 1796 received the recognition of genius in the defense of Frankfurt and as major in the campaign at the Main river in Germany and during the siege of Kehl.
In 1797 Dedovich was in charge of the buildings in Ulm and the defense of the fortress, and in 1798 he was used by the Imperial Contingent Army and promoted to lieutenant colonel.
When the war was over, Dedovich was promoted to Field Marshal Lieutenant and died as Fortifications District Director in Petrovaradin at the age of 66.
