15 August 1944, right here
Operation Dragoon still sits, in the collective memory, largely in the shadow of the Normandy landings. It was decisive all the same, and it played out on the beaches we know today for entirely other reasons.
In the early hours of 15 August 1944, fifty thousand Allied soldiers landed along the Var coast, between Cavalaire and Saint-Raphaël, taking in Saint-Tropez, Sainte-Maxime and Fréjus. The gulf was at the centre of it. Saint-Tropez was liberated the same day. In the weeks that followed, the push towards the Rhône valley moved faster than anyone had planned for.
The village has commemorated that anniversary every year since. The Allied Marines memorial, where the tribute is paid on the morning of the 15th, marks the part played by naval units in the operation.
This is the only firework display on the coast whose date is explained not by the holiday calendar but by a military operation. Hence the sobriety of the next morning's ceremonies, which sit oddly against the crowd of the night before. And that is the history to carry with you while watching it: it does not celebrate summer, it celebrates a liberation.
