sentences:  On 12 May, members of 127th Infantry Regiment stumbled upon the first lines of Japanese defense, coming under heavy mortar and machine gun fire.However, they managed to fight back and progress several miles beyond the first Japanese defensive line along the old German road and through deep jungle forest located in between the road and the Torricelli Mountains, only to find out that the Japanese were much more numerous and organized than expected, and decided on pulling back on 14 May after heavy Japanese counter attacks.The Japanese, growing increasingly concerned of this threat on their western flank, decided to act on by taking a more offensive stance.
