There were more incidents and in November 1961 the Portuguese in Goa opened fire on Indian fishing boats. Nehru lost patience and mounted a military, naval and air attack on Goa using overwhelming force on December 17th. The Portuguese governor, who had at the most 3,000 men to oppose an Indian army of 30,000, blew up a few bridges to delay the invaders but his situation was plainly hopeless and he hoisted the white flag and surrendered. There had been almost no resistance and few casualties.
