What is siege of suiyang?

The siege of Suiyang took place in 757 during the period of the An Lushan Rebellion in China. Suiyang was a strategically important city located in modern-day Henan province, and it was held by loyalist forces defending the Tang Dynasty against the rebel forces of An Lushan.

The siege of Suiyang lasted for over half a year, from January to July 757, with the rebel forces under An Lushan's son, An Qingxu, leading the attack. The defenders of Suiyang were commanded by Yang Guozhong, a trusted ally of the Tang imperial family.

Despite being vastly outnumbered, the defenders of Suiyang managed to hold out for months against the relentless attacks of the rebel forces. The defenders utilized the city's fortifications and employed various tactics to fend off the besieging army.

However, the rebel forces eventually breached the city's defenses and captured Suiyang in July 757. Yang Guozhong and many of his troops were killed, while others were captured and executed by the rebels.

The siege of Suiyang was a significant event in the An Lushan Rebellion, as it demonstrated the tenacity and bravery of the loyalist forces in defending their stronghold against overwhelming odds. It also marked a turning point in the rebellion, as the fall of Suiyang weakened the Tang Dynasty's grip on central China and paved the way for further rebel advances.
