May 22 in Military History — On This Day

The Night Assault on the Sea Walls

A total lunar eclipse on the night of May 22 terrified the Byzantine defenders — an ancient prophecy held that Constantinople would fall when the moon was full. The Ottomans launched coordinated attacks on the sea walls by both the Golden Horn fleet and the Marmara sea approach, while simultaneously renewing artillery bombardment of the land walls. Byzantine sailors held the sea walls with incendiary weapons and concentrated missile fire. The defenders repulsed the seaborne attacks, but the eclipse's psychological damage was severe: morale collapsed in the city as the population interpreted the darkened moon as divine confirmation of doom.

The lunar eclipse of May 22 was a turning point in the siege's psychological dimension. It was not a military defeat — the defenders held — but the combination of physical exhaustion, irreplaceable casualties, and the terrible omen broke the civilian population's will to resist even as the soldiers continued fighting.

First Battle of St Albans

The opening battle of the Wars of the Roses saw Yorkist forces under Richard, Duke of York, attack the royal procession through the streets of St Albans. The fighting was brief and vicious — Richard of York's ally Richard Neville, Earl of Warwick, broke through the town's back lanes to outflank the Lancastrians. King Henry VI was captured, and the Duke of Somerset — York's chief enemy at court — was killed on the steps of a tavern.

St Albans transformed a political feud into open warfare and gave the Yorkists control of the king's person. Somerset's death removed Henry VI's strongest protector. The battle proved that the political crisis could not be resolved by negotiation alone, setting the template for a conflict that would last thirty years.

The Toxcatl Massacre and the Uprising

While Cortés was on the coast, Alvarado's garrison surrounded the unarmed celebrants of the festival of Toxcatl in the Great Temple precinct and killed them — the flower of Tenochtitlan's nobility, cut down at a religious festival they had been given permission to hold. The city rose immediately, penned the Spanish in their compound, and elected Cuitláhuac to lead the war.

Alvarado destroyed in an afternoon what Cortés had spent six months building. Moctezuma, brought out to calm the crowds, was stoned by his own people and died days later; the hostage strategy was finished. From this moment the Spanish were not guests in Tenochtitlan but a trapped garrison in a hostile city.

Stonewall Jackson's Valley Campaign Peaks

During his brilliant Valley Campaign, Stonewall Jackson's small army of 17,000 tied down 60,000 Union troops through a series of rapid marches and surprise attacks, preventing them from reinforcing McClellan's assault on Richmond.

Jackson's Valley Campaign is studied in military schools as a masterpiece of strategic mobility — using a smaller force to neutralize a much larger enemy by keeping it perpetually off-balance.

Outcome

Jackson pins 60,000 Union troops; Richmond protected

Recapture of Khorramshahr

Following the success of Operation Undeniable Victory, Iran recaptured Khorramshahr in a three-day assault. Combined IRGC and regular army forces enveloped the city from multiple directions. Iraqi defenders, trapped in the 'City of Blood,' suffered heavy casualties trying to escape. Iran captured 19,000 Iraqi prisoners — the largest prisoner take of the war. The 'City of Blood' had been reclaimed.

The recapture of Khorramshahr was the high-water mark of Iranian military success and the moment the war could have been ended with honor. Iran had expelled the invaders, liberated its territory, and demonstrated that Saddam's gamble had failed catastrophically. Instead, Khomeini chose to continue the war — demanding Saddam's removal and reparations — transforming Iran's defensive victory into an offensive war that cost hundreds of thousands more lives.
