Geum River
In 658, Emperor Gaozong had sent an army to attack Goguryeo. Shortly afterwards, in 660, he sent a Tang army towards Baekje to further relieve Silla. It comprised 130,000 troops. During this expedition, Admiral Su Dingfang commanded the Tang fleet and sailed it straight towards Baekje. The Tang fleet sailed across the Yellow Sea, towards Geum River, and landed its army on the western coastline of Baekje. After the landing of the army, the Tang troops marched further towards Sabi, the capital of Baekje.
