During the Battle of Xinkou, the Chinese defenders resisted the efforts of Japan's elite Itakagi Division for over a month, despite Japanese advantages in artillery and air support. By the end of October 1937, Japan's losses were four times greater than those suffered at Pingxingguan, and the Itakagi Division was close to defeat. Contemporary Communist accounts called the battle "the most fierce in North China", while Japanese accounts called the battle a "stalemate". In an effort to save their forces at Xinkou, Japanese forces began an effort to occupy Shanxi from a second direction, in the east. After a week of fighting, Japanese forces captured the strategic Niangzi Pass, opening the way to capturing Taiyuan. Communist guerrilla tactics were ineffective in slowing down the Japanese advance. The defenders at Xinkou, realizing that they were in danger of being outflanked, withdrew southward, past Taiyuan, leaving a small force of 6,000 men to hold off the entire Japanese army. A representative of the Japanese Army, speaking of the final defense of Taiyuan, said that "nowhere in China have the Chinese fought so obstinately".
