Dagshai
This India List post advises that Dagshai, together with Kasauli and Subathu, were hill depots created by the British Army in the mid-19th c for the families and some of the troops to escape to in the hot weather which was so unhealthy in the plains. They are on the ridges of wooded hills about 20 kms into the Himalayas on the road between Chandigarh and Simla.
