 Carrying out a number of smaller-scale operations, the units of the 21st and 25th Brigades advanced up the Markham and Ramu Valleys.Apart from a significant engagement around Kaiapit, where the 2/6th Commando Squadron captured the village and killed over 200 Japanese, the Australians were barely resisted as they advanced and they arrived in Dumpu in early October.During the entire advance, the Australian and American forces in the Ramu Valley were supplied by air.
