issued an address to his men: We are very glad and grateful for the opportunity of being able to serve our country in this epic battle. Now, with what strength remains, we will daringly engage the enemy. Banzai to the Emperor! We are determined to fight to the last man. Battle Santo Tomas internees liberated On 3 February, elements of the 1st Cavalry Division under Maj. Gen. Verne D. Mudge pushed into the northern outskirts of Manila and seized a vital bridge across the Tullahan River, which separated them from the city proper, and quickly captured Malacanang Palace. A squadron of Brig. Gen. William C. Chase's 8th Cavalry, the first unit to arrive in the city, began a drive toward the sprawling campus of the University of Santo Tomas, which had been turned into the Santo Tomas Internment Camp for civilians and the US Army and Navy nurses sometimes known as the "Angels of Bataan". Since 4 January 1942, a total of thirty-seven months, the university's main building had been used to hold civilians.
