The Australian 7th Infantry Division was tasked to execute Oboe 2, the operation to take Balikpapan. The initial landings were made on 1 July at Klandasan on the south coats. The beachhead was secured, and the Japanese began to withdraw to better defensive positions. The Australians were extremely well-supported with artillery and air support, and continued to press the advance. On 9 July a significant penetration was being made in a general northerly direction, and Company A was ordered to take Coke Hill in the afternoon. They were reinforced by two Matildas and a Matilda Frog from the 4th Armoured Brigade.
