The Siege of Cuautla during the Mexican War of Independence ends with both sides claiming victory.

The Mexican War of Independence was a pivotal conflict that lasted from 1810 to 1821 and led to Mexico gaining independence from Spanish colonial rule.

Beginnings: The war began on September 16, 1810, when Miguel Hidalgo y Costilla, a Catholic priest, issued the “Grito de Dolores” (Cry of Dolores), calling for the end of Spanish rule in Mexico. This event, which took place in the small town of Dolores, in the present-day state of Guanajuato, marked the start of the uprising.

Key Figures: Alongside Miguel Hidalgo, other important leaders included José María Morelos, Vicente Guerrero, and later, Agustín de Iturbide. These leaders played crucial roles in various phases of the war, with Morelos and Guerrero continuing the fight after Hidalgo’s capture and execution in 1811.

Phases of the War: The conflict can be broadly divided into several phases. The initial phase was characterized by significant gains by the insurgents, but after Hidalgo’s death, the movement suffered setbacks. Morelos managed to formalize the insurgency by convening Congresses and drafting constitutions but was captured and executed in 1815. The latter stages saw a revival under leaders like Guerrero and Guadalupe Victoria.

Plan of Iguala and Treaty of Córdoba: The final phase of the war was marked by a change in strategy. In 1821, Agustín de Iturbide, a former royalist who switched sides, formulated the Plan of Iguala, which proposed an independent Mexico governed as a constitutional monarchy. This plan gained wide support and led to the signing of the Treaty of Córdoba with the last viceroy of New Spain, confirming Mexico’s independence.

Outcome and Legacy: The war officially ended on September 27, 1821, when the Army of the Three Guarantees (reflecting the main points of the Plan of Iguala: religion, independence, and unity) entered Mexico City. The aftermath of the war was marked by political instability and power struggles, culminating in Iturbide declaring himself emperor, a reign that was short-lived. Despite these challenges, the war set the foundation for Mexico as an independent nation with its own identity.

The Treaties of Orebro end both the Anglo-Russian and Anglo-Swedish Wars.

The Treaty of Orebro was signed on July 18, 1812, between Sweden and the United Kingdom during the Napoleonic Wars. It was one of the peace treaties that followed the conclusion of the Anglo-Russian War (1812) and the Finnish War (1808-1809).

The treaty aimed to establish peace between the two nations, as well as secure British support for Sweden in the event of any future military aggression from France or its allies. At the time, Sweden was concerned about its territorial integrity and sovereignty, particularly due to the influence of Napoleon Bonaparte’s French Empire in Europe.

One of the main provisions of the treaty was the establishment of the border between Swedish Pomerania and the Kingdom of Prussia. Sweden ceded the town of Stralsund and the island of Rugen to Prussia in exchange for an agreement of British military support in case of any foreign attack on Sweden.

26 March 1812

An earthquake devastates Caracas, Venezuela.

The 1812 Caracas earthquake took place in Venezuela on March 26 on Maundy Thursday at 4:37 p.m. It measured 7.7 on the Richter magnitude scale. It caused extensive damage in Caracas, La Guaira, Barquisimeto, San Felipe, and Mérida. An estimated 15,000–20,000 people perished as a result, in addition to incalculable material damage.

The seismic movement was so drastic that in a zone named Valecillo a new lake was formed and the river Yurubí was dammed up. Numerous rivulets changed their course in the valley of Caracas, which was flooded with dirty water.

Based on contemporary descriptions, the earthquake is believed to have consisted of two seismic shocks occurring within the span of 30 minutes. The first destroyed Caracas and the second Mérida, where it was raining when the shock occurred.

Since the earthquake occurred on Maundy Thursday, while the Venezuelan War of Independence was raging, it was explained by royalist authorities as divine punishment for the rebellion against the Spanish Crown. The archbishop of Caracas, Narciso Coll y Prat, referred to the event as “the terrifying but well-deserved earthquake” which “confirms in our days the prophecies revealed by God to men about the ancient impious and proud cities: Babylon, Jerusalem and the Tower of Babel”.

The first international assistance received by Venezuela in response to the earthquake came from the United States, “…when the congress convened in Washington decreed unanimously the sending of five ships loaded with flour, to the coasts of Venezuela to be distributed among the most indigent of its inhabitants.

Napoleon’s army is defeated at the Battle of Vyazma.

The Battle of Vyazma, occurred at the beginning of Napoleon’s retreat from Moscow. In this encounter, the rear guard of the Grande Armée was defeated by the Russians commanded by General Mikhail Andreyevich Miloradovich. Although the French repelled Miloradovich’s attempt to encircle and destroy the corps of Louis Nicolas Davout, they withdrew in a partial state of disorder after suffering heavy casualties from continued Russian attacks.

The French reversal at Vyazma was not decisive, but it was noteworthy because of its disruptive impact on the Grande Armée’s retreat.

Miloradovich’s cavalry attacked the disorganized French column holding the length of road which separated the I Corps from the IV and V Corps. Miloradovich also ordered his artillery, positioned on nearby heights, to begin a cannonade. The attack was a complete success, as it captured the French IV Corps baggage train and sent the French troops fleeing in disarray. Miloradovich then placed infantrymen and horse batteries astraddle the road, thereby severing Davout’s connection with the rest of the French army.

Simultaneous to Miloradovich’s attack to the west of Davout, Platov’s Cossacks attacked Davout from the east, supported by Paskevich’s troops. Davout’s infantrymen formed squares to meet the attack from Platov and Paskevich, and his artillerymen set up their pieces to return Miloradovich’s fire. The 14,000 exhausted, hunger-weakened soldiers of Davout’s Corps were now at risk of being overwhelmed and destroyed by the Russians.

Napoleon Bonaparte retreats from Moscow.

The story of Napoleon’s advance to and retreat from Moscow, is one of the most pathetic in human history. Full of spirit, the Grand Army had started, but already difficulties were beginning. It took three days to cross the Niemen, by means of pontoon bridges thrown across; but they reached the far side unmolested, and pursued their way over the sandy wastes. The solitude of the way, the sultry heat of a Russian midsummer, and drenching thunderstorms depressed the spirits of the army.

During the disastrous retreat, Napoleon’s army suffered continual harassment from a suddenly aggressive and merciless Russian army. Stalked by hunger and the deadly lances of the Cossacks, the decimated army reached the Berezina River late in November but found its route blocked by the Russians. On November 26, Napoleon forced a way across at Studienka, and when the bulk of his army passed the river three days later, he was forced to burn his makeshift bridges behind him, stranding some 10,000 stragglers on the other side. From there, the retreat became a rout, and on December 8 Napoleon left what remained of his army to return to Paris with a few cohorts. Six days later, the Grande Armée finally escaped Russia, having suffered a loss of more than 400,000 men during the disastrous invasion.

Twenty four settlers are killed during the Pigeon Roost Massacre in Indiana.

On September 3, 1812, a war party of Native Americans made a surprise attack on the village. Twenty-four settlers, including fifteen children, were massacred. Two children were kidnapped. Only four of the Indian attackers were killed.

According to contemporary reports, the leader of the attack was rumored to be an Indian named Missilemotaw. He was captured on September 20, 1813 and under threat of death confessed he had led the raid. He claimed to be a close confidant of the Indian chieftain and told his captors the British had been supplying the Indians with arms and equipment since 1809 in preparation for war.The raid was the first Indian attack in Indiana during the War of 1812. The Pigeon Roost settlement was rebuilt, but was eventually abandoned.
