鄭檢
In 1570, Trịnh Kiểm died. Anh Tông appointed Kiểm's eldest son, Trịnh Cối as Generalissimo, controlling both the government and army of the Lê realm. Trịnh Cối soon proved to be an incompetent ruler, and was overthrown by his younger brother Trịnh Tùng. Under the resourceful command of Trịnh Tùng and Lê Cập Đệ, Lê forces repelled an offensive of Mạc Kính Điển in Thanh Hóa lowlands in 1570.
