In February 1570, Trịnh Kiểm has died, so emperor Lê Anh Tông gave Trịnh Cối the authority with new title Duke Đạt Nghĩa (義達公). However, some officials and generals didn't comply with Trịnh Cối, so they supported his younger brother Trịnh Tùng. April 1570, officials Lê Cập Đệ, Trịnh Vĩnh Thiệu, Trịnh Bách, Phan Công Tích with their inferiors went to Trịnh Tùng's house and advised him to plot a coup d'état. At first Trịnh Tùng pretended refusing for the suffering, then he agreed completely.
After the Northern dynasty heard the news about a confusion in Thanh Hoa, Emperor Mạc Mục Tông had assigned Prince Mạc Kính Điển to lead 100,000 soldiers with 700 warships to attack Southern dynasty. In August 1570, all of Thanh Hoa produced a stir.
Mạc forces came on waterfronts Linh Tràng, Chi Long, Hội Triều and occupied Bút Cương village easily and quickly. Northern dynasty garrisoned in Hà Trung, both parties faced about 10 miles. So Trịnh Cối was caught between Mạc forces and Trịnh Tùng, and he was reluctant to surrender to Mạc Kính Điển.
Immediately the Mạc forces cancelled marching orders, Trịnh Cối directed his mother, wives, children and inferiors about 1,000 persons to follow marshal Mạc Kính Điển in the backing Đông Kinh. Emperor Mạc Mục Tông had conferred him a title Marquis Trung Lương (中良侯) and his inferiors "duke". All of them had been banished to the capital.
A surrender made Trịnh Cối to be slighted by Lê dynasty's records, Trịnh clan annals haven't even recognize him as the leader of Southern dynasty. He was only recognized by Nguyễn dynasty's records. However, contemporary lord Trịnh Tráng (son of lord Trịnh Tùng) still conferred a posthumous title Archduke Trung Lương (忠國公).
