1347: In Brittany, Charles de Blois had laid siege the previous month to the English stronghold of La Roche-Derrien on the north coast of the peninsula, defended by Richard Totesham. Charles' aim was probably to draw out the small army of Sir Thomas Dagworth, the senior English captain in the province. Dagworth responded by mustering about 300 men-at-arms and 400 archers from his other garrisons and marching to an abandoned monastery a few miles from the siege. Scouts having reported that Charles' much larger army was potentially vulnerable, spread quite thinly around La Roche-Derrien, Dagworth set out on a night march and hit the French army before dawn. The first attack failed, with Dagworth himself being captured in the confusion. But as dawn came up, Totesham's garrison was able to see the situation, and sortied, accompanied by some of the Breton townsmen. Their attack caught Charles' troops in the rear and rescued Dagworth. A detachment of Flemish mercenaries in English pay then cornered Charles himself and eventually took him prisoner after a ferocious fight which left de Blois with seven wounds. His army had lost over half its men, and most of his senior nobles and gentry had been captured or killed.

1783: Off the coast of Decca, Rear-Admiral Sir Edward Hughes and Chef d'Escadre de Suffren fought a further round in their epic series of battles for control of the Indian Ocean.

1858: At Gwalior, Lieutenant Waller led loyal Indian troops in a successful assault on a fort held by Mutineers. He was awarded the Victoria Cross.

1943: Sixty Lancaster aircraft of Bomber Command's 5 Group attempted a night precision attack against a factory at the Zeppelin works on the shores of Lake Constance, constructing German radar sets. Following the success of Wing Commander Gibson's direct control of 617 Squadron's attack on the Ruhr dams the previous month, a further experiment was made with a pilot acting as "master of ceremonies" over the target - a technique that was to be fully developed into the Master Bomber methods used later in the war. Heavy anti-aircraft fire forced the attackers to bomb from a higher altitude than planned, and the target itself could not be picked out. But by conducting a timed run from an identifiable landmark on the lake shores, the Lancasters still managed to get 10% of the bombs directly onto the factory, which was badly damaged. The aircraft then flew on to land at bases in North Africa, avoiding German night-fighters massing over France expecting a return flight to the UK.

1982: South Thule was liberated as the last act in the Falklands campaign.
