1778 – ARW: British and French fleets clash in the Battle of St. Lucia

15 December

The Battle of St. Lucia was a naval battle fought off the island of St. Lucia in the West Indies during the Anglo-French War on this day in 1778, between the British Royal Navy and the French Navy.

On 7 September 1778, the French governor of Martinique, the marquis de Bouillé, surprised and captured the British island of Dominica. On 4 November, French Admiral Jean Baptiste Charles Henri Hector. comte d'Estaing sailed for the West Indies from the port of Boston. On that same day, Commodore William Hotham was dispatched from Sandy Hook, New York, to reinforce the British fleet in the West Indies. Hotham sailed with "five men of war, a bomb vessel, some frigates, and a large convoy." The convoy Hotham was escorting consisted of 59 transports carrying 5,000 British soldiers under Major General Grant. The French fleet was blown off course by a violent storm, preventing it from arriving in the Caribbean ahead of the British. Admiral Samuel Barrington, the British naval commander stationed on the Leeward Islands, joined the newly arrived Commodore Hotham on 10 December at the island of Barbados. Grant's men were not permitted to disembark and spent the next several days aboard their transports. Barrington and Hotham sailed for the island of St. Lucia on the morning of 12 December.

On the evening of 13 December and morning of 14 December, Major General James Grant, supported by additional troops under Brigadier General William Medows and Brigadier General Robert Prescott, landed at Grand Cul de Sac, St. Lucia. Grant and Prescott took control of the high ground around the bay, while Medows continued on and took Vigie the following morning (14 December). On 14 December the French fleet under d’Estaing arrived, forcing Admiral Barrington to move his ships into line of battle and forgo his plan of moving the transports into Carénage Bay.

Admiral Barrington was alerted to the presence of the French fleet by the frigate Ariadne and organised his line of battle so that Isis and his three frigates (Venus, Aurora, and Ariadne) were close to shore guarding the windward approach, and he placed his flagship, Prince of Wales, toward the leeward. Barrington in a defensive strategy placed his transports inside the bay but behind his battle line which took him the entire evening of 14 December. By 1100 hours the next day, most of the transports had been safely tucked behind his line.

At 1100 hours 15 December Admiral d’Estaing approached St. Lucia with ten ships of the line, and was fired on by one of the shore batteries. D’Estaing then moved to engage Barrington from the rear, and a “warm conflict” raged between the two fleets, with the British supported by two shore batteries. D’Estaing was repulsed but succeeded in reforming his line of battle. At 1600 hours d’Estaing renewed his assault by attacking Barrington’s centre with twelve ships of the line. Again, heavy fire was exchanged and the French were eventually repulsed for a second time.

On 16 December Admiral d’Estaing appeared to be preparing for a third assault against Admiral Barrington’s line, but then sailed away towards the windward. On the evening of 16 December d’Estaing anchored in Gros Islet Bay with "ten frigates and twelve sail of the line, &c." Admiral d’Estaing’s failure to break Barrington’s line on 15 December spelled doom for the local French garrison, which surrendered on 28 December.

1854 – Battle of the Eureka Stockade

3 December

The Eureka Stockade in 1854 was a rebellion of gold miners of Ballarat, Victoria, Australia, who revolted against the colonial authority of the United Kingdom. The Battle of the Eureka Stockade, was fought between miners and the Colonial forces of Australia on this day in 1854 at Eureka Lead and named for the stockade structure erected by miners during the conflict. The rebellion lasted for less than half an hour and resulted in the deaths of at least 27 people, the majority of whom were rebels.

The event was the culmination of a period of civil disobedience in the Ballarat region during the Victorian gold rush with miners objecting to the expense of a miner's licence, taxation via the licence without representation and the actions of the government, the police and military. The local rebellion grew from a Ballarat Reform League movement and culminated in the erection by the rebels of a crude battlement and a swift and deadly siege by colonial forces.

Mass public support for the captured rebels in the colony's capital of Melbourne when they were placed on trial resulted in the introduction of the Electoral Act 1856, which mandated full white male suffrage for elections for the lower house in the Victorian parliament, the second instituted political democracy in Australia. As such, the Eureka Rebellion is controversially identified with the birth of democracy in Australia and interpreted by some as a political revolt.

1899 – Philippine–American War: The Battle of Tirad Pass

2 December

The Battle of Tirad Pass sometimes referred to as the "Philippine Thermopylae", was a battle in the Philippine-American War fought on this day in 1899, in northern Luzon in the Philippines, in which a 60-man Filipino rear guard commanded by Brigadier General Gregorio del Pilar succumbed to over 500 Americans, mostly of the 33rd Infantry Regiment under Major Peyton C. March, while delaying the American advance to ensure President Emilio Aguinaldo's and his troops to escape.
