The Supreme Allied Commander Atlantic (SACLANT) was one of two supreme commanders of the North Atlantic Treaty Organisation (NATO), the other being the Supreme Allied Commander Europe (SACEUR). The SACLANT led Allied Command Atlantic was based at Norfolk, Virginia. The entire command was routinely referred to as 'SACLANT'. In 1981 SACLANT's wartime task was listed as being to provide for the security of the area by guarding sea lanes to deny their use to an enemy and to safeguard them for the reinforcement and resupply of NATO Europe with personnel and materiel.The command's area of responsibility extended from the North Pole to the Tropic of Cancer as well as extending from the east coast of North America to the west coast of Africa and Europe, including Portugal but not the English Channel, the British Isles, and the Canary Islands.Allied Command Atlantic was redesignated as Allied Command Transformation (ACT) on 19 June 2003. ACT was to be headed by the Supreme Allied Commander Transformation (SACT), up to 2009 an American four-star admiral or general who was dual-hatted as commander, United States Joint Forces Command (COMUSJFCOM). SACLANT's former military missions were folded into NATO's Allied Command Operations (ACO).

Allied Command Transformation (ACT) (French: Commandement allié Transformation) is a military command of the North Atlantic Treaty Organization (NATO), formed in 2003 after restructuring. It was intended to lead military transformation of alliance forces and capabilities, using new concepts such as the NATO Response Force and new doctrines in order to improve the alliance's military effectiveness. When France rejoined the NATO Military Command Structure in mid-2009, a significant change took place where the Supreme Allied Commander Transformation (SACT) became a French officer. The first French officer to serve as SACT was French Air Force General Stephane Abrial (2009–2012).

Saint-Denis (French pronunciation: [sɛ̃ dəni] ; Walloon: Sint-Dnis) is a sub-municipality of the city of Mons located in the province of Hainaut, Wallonia, Belgium. It was a separate municipality until 1964. In 1964, it was merged into Obourg. On 1 January 1972, Obourg was merged into Mons.

The Battle of Saint-Denis was the last major action of the Franco-Dutch War (1672-78). It took place on 14 August 1678, four days after Louis XIV of France had agreed the Treaty of Nijmegen with the Dutch Republic, but before he finalised terms with Spain. The battle was initiated by the Dutch and Spanish forces to prevent the French capturing the Spanish-held town of Mons, then on the border between France and the Spanish Netherlands. The result was disputed, as both sides claimed victory. Leaving a small force to maintain the siege of Mons, French commander Luxembourg concentrated 40,000 to 50,000 men around the nearby villages of Saint-Dénis and Casteau, where they were attacked by a combined Dutch-Spanish army of 35,000 to 45,000 men led by William of Orange. In the early stages, the Allies overran the French flanks and forced Luxembourg out of his headquarters in the abbey of Saint-Dénis, but were then pushed back by a series of counter attacks, with many positions changing hands several times. Fighting continued late into the evening, when William pulled his troops back to regroup, leaving the French occupying most of their original lines. The exception was Saint-Denis, whose loss left the French position untenable. When the Allies resumed their attack early next morning, they found Luxembourg had withdrawn overnight and abandoned the siege of Mons. As a result, the town remained Spanish under the treaty agreed with Louis XIV on 17 September.

Obourg (French pronunciation: [ɔbuʁ]; Walloon: Obour) is a sub-municipality of the city of Mons located in the province of Hainaut, Wallonia, Belgium. It was a separate municipality until 1972. In 1964, Saint-Denis was merged into Obourg. On 1 January 1972, Obourg was merged into Mons.

The length of the river between the spring and the river Haine is about 20 kilometres (12 mi). Sometimes the river is named Aubrecheuil. Around the river is a fertile valley known as a centre for growing chicory, hops, and earlier in the 20th century tobacco.
