Dieppe
First recorded as a small fishing settlement in 1030, Dieppe was an important prize fought over during the Hundred Years' War.
Dieppe housed the most advanced French school of cartography in the 16th century. Two of France's best navigators, Michel le Vasseur and his brother Thomas le Vasseur, lived in Dieppe when they were recruited to join the expedition of René Goulaine de Laudonnière which departed Le Havre for Florida on April 20, 1564. The expedition resulted in the construction of Fort Caroline, the first French colony in the New World. Another expedition two years before where Goulaine de Laudonnière was under command of Jean Ribault, a local Huguenot captain, had resulted in the foundation of Charlesfort, now in South Carolina. Dieppe was the premier port of the kingdom in the 17th century.
On July 23, 1632, 300 colonists heading to New France departed from Dieppe.
At the Revocation of the Edict of Nantes in 1685, Dieppe lost 3,000 of its Huguenot citizens, who fled abroad.
Gap, Hautes-Alpes
The 16th and 17th centuries were particularly dark times for the city. The Wars of Religion were lethal in the region. Gap was a Catholic stronghold, while the switched to Protestantism. After various skirmishes, François de Bonne, leader of the Protestants, decided to attack Gap, nevertheless protected by 20 towers. On the night of 3 January 1577, François Philibert, known as "Cadet de Charance", opened the Saint-Arey gate, and allowed him to attack the city by surprise. To cries of "Kill! Kill!" his men proceeded in veritable butchery. De Bonne burned the cathedral, plundered the monasteries, appropriated the property of the inhabitants, and built a proud citadel on the "Colline de Puymaur"e [Puymaure Hill] where it dominated over Gap. Returned to Catholicism in 1622, he abandoned all claims to the city.
