This victory was considered so important (as no doubt it was) that we find the church celebrating it in a song of praise in one Psalm, and echoing to the same again in another. See Psalms 125:5, and Psalms 126:6.
Deuteronomy 3:3-10
3 So the LORD our God delivered into our hands Og also, the king of Bashan, and all his people: and we smote him until none was left to him remaining.
4 And we took all his cities at that time, there was not a city which we took not from them, threescore cities, all the region of Argob, the kingdom of Og in Bashan.
5 All these cities were fenced with high walls, gates, and bars; beside unwalled towns a great many.
6 And we utterly destroyed them, as we did unto Sihon king of Heshbon, utterly destroying the men, women, and children, of every city.
7 But all the cattle, and the spoil of the cities, we took for a prey to ourselves.
8 And we took at that time out of the hand of the two kings of the Amorites the land that was on this side Jordan, from the river of Arnon unto mount Hermon;
9 (Which Hermon the Sidonians call Sirion; and the Amorites call it Shenir;)
10 All the cities of the plain, and all Gilead, and all Bashan, unto Salchah and Edrei, cities of the kingdom of Og in Bashan.
