Childers Incident

Îlot des Capucins (Islet of the Capuchins) is a rocky islet at the foot of a cliff in the commune of Roscanvel on the Crozon peninsula. Its name comes from a rock near the island, shaped like a praying monk. It has a strategic position at the entrance to the goulet de Brest and so a fort sited on it controlled the whole of Camaret Bay, with views stretching from pointe du Grand Gouin (to the southwest), to fort de Bertheaume (to the northwest). The fort was built in 1848 after plans drawn 150 years earlier by Vauban, built in schist and granite and made up of an underground battery (1890) and a rapid-fire battery (1890) It was linked to the mainland by a bridge in 1859.On the heights overlooking the islet is an upper battery (1885) to the islet's right and left, a platform battery with an underground magazine (1897) and a mortar battery (1889).

The batteries de Kerviniou are artillery batteries built in the late 19th and early 20th centuries, and are made up of an upper battery (1891) and an underground magazine (1891) Located on the Roscanvel peninsula facing the Fort du Mengant, they are a late addition to the defences of the goulet de Brest (a lower battery near the site, dating to 1695, has not yet been found). Demilitarised in 1915, they are open to the public.

Îlot du Diable is a gun battery built to support fort de la Fraternité in the defensive system around the goulet de Brest in France. It is sited on the peninsula of Roscanvel and is accessible by a small bridge. The battery was razed in the 19th century, and in 1890 on its site was built a bunker with an electricity generator. A casemate was then added by the Germans in 1942. A small observation is still to be found at the summit of the site, near a former lime kiln.

Built between 1694 and 1697, the Fort du Petit Minou was a fort built in the commune of Plouzané in France to defend the goulet de Brest. It consists of 6m high masonry bastions, surrounded by a 3m deep and 9.5m wide moat. Vauban completed the defences along the goulet and at this fort installed 240 cannons and a command post for directing fire and coordinating the defences' magazines. It was reinforced in the 18th and 19th centuries, with the phare du Petit Minou being added nearby in 1848. The fort was occupied in 1940 as a German blockhouse and after the point's liberation at the start of September 1944 the remains of a former hôtel were demolished. After losing its military purpose, the fort was acquired by the commune and opened to the public in October 2007.

The pointe du Grand Gouin is a rocky promontory with vertical cliffs to the west of the inlet of Camaret-sur-Mer in France. It protects a port which, in Vauban's era, was vulnerable to possible landings. It is divided into the Grand Gouin (the top of the cliff) and the Petit Gouin (mid-cliff).

La pointe de Cornouaille is a cape to the north of the hamlet of Kerviniou in France. They are both situated on the Roscanvel peninsula and, facing as it does the Fort du Mengant, a battery on the point forms part of the defences of the goulet de Brest. Known defences on the site include: Lower battery (1694) - built to plans by Vauban Tour modèle n°1 (1813) - see Tour-modèle type 1811 Batterie de rupture sous roc (1888) Batterie du plateau (1897) Batterie de DCA allemande (1943, German) Torpedo-boat battery (German)

Le Minou is the site of a popular surfing beach and a lighthouse at the entrance to Brest harbor in France. It is part of the commune of Plouzané, on the north side of the Goulet de Brest. "Le Minou" means "pussy cat" in French. Le Minou is the site of the landfall of the first French transatlantic telegraph cable in 1869.

Tremet is a hamlet on the Roscanvel peninsula in France. The gun batteries located here are part of the defences of the goulet de Brest, forbidding ships from entering the bay of Camaret-sur-Mer. The site had been occupied by the military since 1694 (a battery was probably sited here in Vauban's defensive scheme) and was updated several times in the 18th and 19th centuries. The battery became a heavy anti-aircraft post in 1955 as part of the outer defences of Brest's military fort - part of that battery is still part of the military land around Quélern and not open to the public.

The fort du Mengant or fort du Léon in the commune of Plouzané is part of the defences of the roadstead of Brest. It is made up of a high battery (58m above sea-level), with a now-destroyed artillery tower, and a lower semi-circular battery at the foot of the cliff, with two small powder magazines. Built by Vauban in 1684, it faces the batterie de cornouaille on the Roscanvel peninsula, built to the same model as the lower part of the fort du Mengant. The aim was to permit these two batteries, only just over 2 km apart, to bar entry to the roadstead. The original plans foresaw the completion of the defences by adding a battery in the middle of the goulet, on the Roche Mengant, but this proved impossible due to the tides and currents in the goulet. Around 1875, the naval ministry built a dam up against the lower battery to create a small harbour in which to base motor torpedo boats, in order to adapt the fort to this evolution in warfare. The lower battery houses the annexe to the Centre Nautique des Equipages de la Marine, whilst the upper battery is now used for radar testing. An imposing ramp was built in the 1960s to link the port to the upper battery so that the largest pieces of radar equipment to be tested could be carried up to it from the port.

Camaret Bay (French: Anse de Camaret) is a small bay on the north coast of Brittany, France. In 1694 it was the site of the battle of Camaret, a naval action between French and English forces, which culminated in a disastrous amphibious landing by the English as part of an attempt to seize the nearby port of Brest.

The Tour Vauban (Vauban Tower), initially known as the tour de Camaret, is an 18m-high polygonal defensive tower built to a plan by Vauban on the Sillon at Camaret-sur-Mer, as part of the fortifications of the goulet de Brest. It has three levels and is flanked by walls, a guardhouse and a gun battery which can hold 11 cannons as well as a cannonball foundry added in the French Revolution period. Drafted in 1683, the tower was designed in 1689 by Vauban and construction was supervised by the military engineer Jean-Pierre Traverse from 1693 to completion in 1696. The 11 cannons in the battery are believed to have been forged with those for the battery on pointe du Grand Gouin, for the Quélern defensive-lines and the many neighbouring batteries. In the French victory in the Battle of Camaret on 18 June 1694, the battery and its two guard houses were only armed with nine 24-pounder cannon and three mortars firing 30 cm balls. On 18 June 1694 Vauban himself was in command of the garrison when they repelled an Anglo-Dutch attack. The battery put several British vessels out of action. On land, a charge by French dragoons scattered the British troops that had landed, and the local militia helped complete the victory. The French claimed to have killed 1200 attackers and captured 450 prisoners. Vauban's forces claimed to have only suffered 45 men wounded. British estimates were that they had lost 700 soldiers killed, wounded, and captured, and that 400 men aboard the ships were killed or wounded. A Dutch frigate of 20 guns also was sunk.The Anglo-Dutch fleet anchored between Camaret Bay and Bertheaume. Consequently, Tour Vauban also received some support from Fort de Bertheaume on the opposite side of the Goulet de Brest. Camaret-sur-Mer is a member of the network of major Vauban sites. Since 7 July 2008 the tour Vauban and 11 other sites have been classified as a UNESCO World Heritage Site due to their outstanding engineering and testimony to Vauban's influence on military strategy and architecture from the 17th through the 19th centuries.

The fort Quélern or réduit de Quélern is a castle and prison in the commune of Roscanvel in France.
