The Ummayad forces suffer a deceisive defeat against the pro-Alid forces under Ibrahim ibn al-Ashtar in the battle of Khazir.
In 686, Ummayad forces were decisively defeated by pro-Alid troops under Ibrahim ibn al-Ashtar at the Battle of Khazir. This clash weakened Ummayad control in Mesopotamia.
On August 6, 686, the Ummayad army suffered a crushing defeat at the hands of pro-Alid forces led by Ibrahim ibn al-Ashtar near the Khazir River. The battle was part of the wider Second Fitna, a civil war that threatened the early Islamic caliphate's stability. Ibrahim ibn al-Ashtar, a loyal supporter of Caliph 'Ali's descendants, ingeniously executed ambush tactics against the larger Ummayad contingent. News of the defeat spread quickly, shaking the confidence of Ummayad authority in Iraq. The Ummayad prince Ubayd Allah ibn Ziyad narrowly escaped with his life, and many of his troops were killed or captured. This setback emboldened other pro-Alid factions and delayed the Ummayads' consolidation of power. Historians view the Battle of Khazir as a turning point that exposed the vulnerabilities of the Ummayad military machine.

In 1284, the Republic of Genoa defeated Pisa at the Battle of Meloria, ending Pisa's Mediterranean naval dominance.
On August 6, 1284, the Genoese fleet won a decisive victory over Pisa near Meloria, a small rocky islet off the Tuscan coast.

Genoa's superior seamanship and innovative tactics overwhelmed Pisa's ships, many of which were captured or sunk. The defeat shattered Pisa's naval power and led to the city's rapid political and economic decline. Prisoners from the battle were paraded through Genoa as trophies of war. Over the following decades, Pisa lost its territories and commercial influence, while Genoa rose to become the preeminent maritime force in the western Mediterranean. Today, the Battle of Meloria is remembered as a key event that reshaped the balance of power among Italian city-states in the Middle Ages.

American Revolutionary War: The bloody Battle of Oriskany prevents American relief of the Siege of Fort Stanwix.
The Battle of Oriskany on August 6, 1777 was one of the bloodiest engagements of the American Revolutionary War, halting relief efforts to Fort Stanwix.
On August 6, 1777, Patriot militiamen clashed with Loyalist forces and their Iroquois allies at Oriskany, New York. The ambush in a dense forest resulted in heavy casualties on both sides, making it one of the war's bloodiest battles.

Despite severe wounds and dwindling ammunition, the Patriots held their ground and forced the Loyalists into retreat. The battle weakened British-aligned Native American support and disrupted Sir John Burgoyne's campaign in the Hudson Valley. Although the Patriots did not immediately reach Fort Stanwix, their stand at Oriskany boosted morale and demonstrated colonial resolve. Today, the battle is commemorated for its fierce combat and its role in turning the tide of the Saratoga campaign.
