During the long campaign, the Indian Army lost 76 officers, 31 JCOs and 996 Other Ranks killed, making a total of 1103. The wounded totalled 3152, including 81 officers and 107 JCOs. Apart from these casualties, it appears that the J & K State Forces lost no less than 1990 officers and men killed, died of wounds, or missing presumed killed. The small RIAF lost a total of 32 officers and men who laid down their lives for the nation during these operations. In this roll of honour, there were no less than 9 officers.
Indian forces won control of most of Kashmir
Nehru therefore suggested to Patel that the maharaja should 'make friends with the National Conference, 'so that there might be this popular support against Pakistan'.

In the first Kashmir war, India occupied two-thirds of the disputed territory and Pakistan was clearly defeated during its first war with India.
India won, and gained two-thirds of Kashmir, which it successfully held against another Pakistani invasion in 1965.
