The battalion was deployed in September 1965 as part of Operation Grand Slam, relieving the 13th Punjab battalion near Dalpat-Chak Kirpal. According to Brigadier Rizvi, the battalion attacked towards Fatwal along with 13 Lancers, advancing up to 6 miles near Kasur and suffering 9 killed and 21 wounded. However, records list the battalion as losing either 9, 11, or 10 killed. The battalion had little impact as it joined the war late when the focus had shifted, and did not receive any awards despite actions in the Rann of Kutch prior to the war.
