August 1944. Since 1940, Paris is occupied by German troops. As the Allied army approaches the capital, this encourages the Parisian population to resist. It comes to a general strike, followed by open revolts. Everywhere in the city (such as here in the rue St. Placide) barricades are erected, and around the 20th of August, the Resistance has taken control of the city. Although militarily inefficient, these barricades had symbolic character for of the Paris uprising.
