Resistance fighters with the French Forces of the Interior armbands meet up with curious recently arrived American troops on the beach in the Saint Tropez area during Operation Dragoon landings along the French Riviera, 15 August 1944. The irregulars of the FFI numbered an estimated 400,000 by this stage of the war and were no longer underground.

The Resistance members all seem to have pistols stuck in their waist-band, channeling Dan Tanna long before the 1970s.

The fella to the left has a Colt M1908 Hammerless stuck in his belt while his buddy with the short (German surplus?) wool jacket has what appears to be an Astra 400 grip just showing. The stabby guy with the bandana has what looks like a 6.35mm pocket pistol such as a Browning Baby or Colt Vest model in addition to his steel-handled sheath knife.
As for the GIs, the older Soldier on the right has the distinctive seahorse patch of the 36th Engineer Regiment.
The 36th Engineers were everywhere in the ETO, earning campaign streamers for Algeria-French Morocco, Tunisia, Sicily, Naples-Foggia, Anzio, and Rome-Arno in the 22 months prior to the Dragoon landings. They would go on to prove essential in the push through Northwest Europe through Alsace and the Rhineland. An active-duty unit, after WWII they went on to serve in Korea, where they remained for 20 years. Reformed as the 36th Engineer Group in 1973 and as the 36th Engineer Group in 2006, they have continued to deploy downrange across the sandbox extensively over the past three decades.
