Flying the Hawker Hunter, La Fontaine was involved in the Indo-Pak Ops of 1965. He led an unfruitful fighter interception sweep over the East Pakistani city of Jessore and an abortive interception to Barrackpore. Aircraft from his unit did take on the Pakistani North American F-86 Sabre over Kalaikunda and No.14 Squadron was the only Hunter unit in 1965 that encountered the enemy Sabres and got the best of them and were still unscathed. Told to lay off operations against targets within East Pakistan, La Fontaine and his team did not see much action later on.
