In 1971, December, 3 the World has become an attestor to a new war between India and Pakistan. At afternoon the Pakistani aviation has strike the Indian cities and airstrips. The Indian PM Indira Gandhi put the country in emergency state and gave the order to nip the aggression. Hard clashes were started on the ground in the air, and at the sea.
Historic document: "Confident. December, 10, 1971. Moscow. For the DM Marshal Andrey Grechko. According to the information from our attaché in Delhi in the first day of conflict the Indian destroyer 'Rajput' has sunk a Pakistani submarine by depth charges. In December, 4 and 9, the Indian fast boats have destroyed and damaged 10 Pakistani battle ships and vessels by the P-15 missiles. In addition 12 oil storages was burned in flame. The Commander of the Military Intelligence Service Gen. Pyotr Ivashutin".
In the same day the Soviet Intelligence has reported that the British Naval group with the leadership of 'Eagle' carrier went closer to the territorial waters of India. The Soviet Government immediately sent a unit of battle ships under the leadership of counter-admiral Vladimir Kruglyakov for helping to the fraternal country.
Vladimir Kruglyakov, the former (1970-1975) Commander of the 10th Operative Battle Group (Pacific Fleet) remembes:
"I received the order from the Chief Commander 'To not allow access of the American Navy to the Indian military objects'.
- On the way of American Navy stood the Soviet cruisers, destroyers and atomic submarines equipped with anti-ship missiles.
Vladimir Kruglyakov, the former (1970-1975) Commander of the 10th Operative Battle Group (Pacific Fleet) remembers:
"We encircled them and I have targeted the 'Enterprise' by missiles. I have blocked them and didn’t allow enclosing to Karachi, nor to Chittagong or Dhaka".
On the Soviet ships then were only the missiles with limited to 300 km range. Thus, to be sure the rival is under the hindsight the Russian commanders have had to take the risk of maximal enclosing to the American fleet.
Vladimir Kruglyakov, the former (1970-1975) Commander of the 10th Operative Battle Group (Pacific Fleet) remembers:
"The Chief Commander has order me: 'Lift the subs when they (the Americans) appear!' – It was done to demonstrate, there are all the needed in Indian Ocean, including the nuclear submarines. I have lifted them, and they recognized it. Then, we intercepted the American communication. The commander of the Carrier Battle Group was then the counter-admiral Dimon Gordon. He sent the report to the 7th American Fleet Commander: 'Sir, we are too late. There are the Russian atomic submarines here, and a big collection of the battleships'.
The war was then two weeks long, and it has finished by Pakistani forces surrendering.
Bangladesh had won the sympathies of the Soviet Union. The Communist country gave support to the Indian Army as well as to the Mukti Bahini. Soviet Union had reasoned that the independence of Bangladesh would weaken both USA and China. Therefore India was assured of Soviet Union’s support in the Indo-Soviet friendship treaty of August 1971.
