In August 1959, the Chinese army took an Indian patrol prisoner at Longju, which falls north of the McMahon Line coordinates drawn on the Simla Treaty, signed in 1914, map (27°44'30" N), but claimed by India to lie directly on the McMahon Line. There was another bloody clash in October at Kongka Pass in Aksai Chin in which 9 Indian frontier policemen were killed. Recognizing that it was not ready for war, the Indian Army assumed responsibility for the border and pulled back patrols from disputed areas.
