Later, it inflicted significant casualties on the Japanese in a series of raids, and led them to believe that they faced a much larger opposing force. On 29 June, the NGVR and the newly arrived &lt;a href="2/5th%20Independent%20Company"&gt;2/5th Independent Company&lt;/a&gt; carried out a highly successful attack on the Japanese garrison in Salamaua, killing at least 113 men. When the focus shifted to the Milne Bay and Kokoda Track battles of August and September, the NGVR continued to man its posts overlooking the Japanese base areas. The Japanese were subsequently defeated in the Battle of Wau in January and February 1943, relieving the pressure on the NGVR. The battalion was disbanded in April 1943 due to attrition.
