Battle of Yique (Chinese: 伊阙之战) 293 BC, fought by King Zhaoxiang of Qin against the alliance of Wei (魏) and Han (韩) at Yique (now known as Longmen, city of Luoyang, Henan province).

In 294 BC Qin, under General Bai Qi, attacked Han and took an important fortress.

The battleground was a vast area including five fortresses, cities, and defensive positions along rivers and mountain ranges.

But the alliance feared Qin's better trained and equipped troops and decided on passive defense.

Bai Qi noticed that Wei and Han were still hostile to each other, so he decided on the divide and conquer strategy.

Both states ceded land to Qin in return for temporary peace, but their eventual destruction was ensured.
