At 1:00 pm on December 10, General Matsui ordered all units to launch a full-scale attack on Nanking. That day the SEA assaulted China's super-elite Training Brigade on the peaks of Zijinshan, which dominate Nanking's northeast horizon. Clambering up the ridges of the mountain, the men of the SEA had to painstakingly wrest control of each Chinese encampment one by one in bloody infantry charges. Advancing along the south side of Zijinshan was no easier as General Matsui had forbidden his men from using artillery there due to his deep conviction that no damage should come to its two famous historical sites, Sun Yat-sen Mausoleum and Ming Xiaoling Mausoleum.
