Supreme Allied Commander Atlantic

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).

The first shot memorial is the common name of a monument in Casteau, Belgium, marking the first British engagement on the Western Front of the First World War. The monument stands near to the start of a charge made by elements of C Squadron of the 4th (Royal Irish) Dragoon Guards, commanded by Captain Charles Beck Hornby, against cavalry scouts from the German 9th Cavalry Division on 22 August 1914. A number of Germans were sabred and captured before the unit came under fire from a larger German force. The British dismounted and returned fire, with Drummer Edward Thomas firing the first shot by British troops on this front of the war, before withdrawing. The monument was designed by an architect from nearby Mons, Mr. Bertiaux, and was unveiled on 20 August 1939, just prior to the 25th anniversary of the action and the outbreak of the Second World War. The monument stands opposite one commemorating the furthest advance by the Canadian 116th Infantry Battalion at the end of the war, 11 November 1918.

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.
