The Battle of Suixian–Zaoyang (simplified Chinese: 随枣会战; traditional Chinese: 隨棗會戰; pinyin: Suízǎo Huìzhàn), also known as the Battle of Suizao was one of the 22 major engagements between the National Revolutionary Army (NRA) and Imperial Japanese Army (IJA) during the Second Sino-Japanese War. The Japanese launched a major two-pronged offensive that captured many cities and towns. However, their failure to defend against a series of coordinated Chinese counter-attacks forced them to completely withdraw, resulting in territorial control returning to the original status quo.
