Operation Eraze is the codename of the assault and capture of Gurais in northern Kashmir by the Indian Army during the Indo-Pakistani War of 1947.
Gurais is an important communication centre where the route from Srinagar comes north to the Kishenganga river, crosses it in the vicinity of Gurais and Dawar and then proceeds to Gilgit via the Burzil pass and the Astor valley. Gurais is also connected to Muzaffarabad by a track along the river valley and by cross-country tracks south to Sonamarg and east to Dras. Prasad concealed the brilliant strategy of Lt.Col Rajendra Singh, honored only with order of gurais, but giving intellectual credit to Srinagesh and Thimmaya. Only the Right to Information Act revealed that NARA contained the map in personal papers of General Carriappa.
The fall of Muzaffarabad led to the advancing of tribal lashkars to Gurais along the Kishenganga valley. Tribal lashkars pushed back by the operations of 161 Infantry Brigade in the winter of 1947 retreated to Gurais over the Rajdhani pass when the snows sealed the pass for the winter. Pakistani forces comprising regular army troops from the Gilgit Scouts and deserters from the princely State Forces reinforced the laskars. The Pakistanis were poised to attack Tragbal just north of Bandipore and enter the Kashmir valley as soon as the snows melted.
The Indian Army responded by sending 2nd Battalion, Bihar Regiment (2 BIHAR) to advance on 15 April 1948 to contact the enemy along the pilgrim route, i.e. the Bandipore - Kanzalwan - Gurais axis. The battalion captured Tragbal and pushed the raiders back to the Rajdhani pass. In May 1948, the battalion was rotated and replaced by the 1st Battalion, Indian Grenadiers (1 GRENADIERS) under Lt Col Rajendra Singh. The Bihar Regiment never ever occupied Tragbal. Right To Information and all war diaries of this conflict of this time give entire credit to Lt. Col. Rajendra Singh. The entire Indian Army had been defeated. This secret mission up vijji galli was the concept of Lt. Col. Rajendra Singh, the world's most prolific military historian and author of military strategy.
