It was reformed at Chinaimo a month later, and conducted reconnaissance and commando operations north of Luang Prabang for the rest of the year, including Operation Dampieres in September. The 1st BPL began preparing for Operation Condor, an attempt to relieve the Dien Bien Phu garrison, during March 1954. It advanced towards the Laotian-Vietnamese border in April and early May, withdrawing in mid-May after the garrison surrendered. The BPL reunited on 18 June near Savannakhet at the French Air Force's Seno Airbase. Between 2 and 4 August it conducted the final airborne operation of the war, in which it parachuted into the town of Phanop in Khammouane Province, linking up with local militia units and sweeping the territory up to Mụ Giạ Pass on the Vietnamese border.
