On 16 Jan 1942, Imperial Japanese Army and allied coalition of Filipino-American forces both raced to capture Morong. Imperial Japanese Army and Allied army reached the town around the same time, but the Allies had detected the Japanese first. Taking the opportunity for a surprise attack, Ramsey ordered his troops to charge forward, more than 20 American cavalry troops charged on their horses, dispersing Japanese troops. It was the last combat charge of horse-mounted American cavalry troops.
