MOSCOW, Dec. 11—The Soviet Union sent a high‐level delegation to India tonight to confer with the Indian Government and possibly leaders of the Bangla Desh (Bengal Nation) independence movement on the military progress of the war against Pakistan and political moves.

The Soviet Government did not announce the trip, but Indian sources said that delegation headed by Deputy Foreign Minister Vasily V. Kuznetsov had flown to New Delhi tonight. It was not known whether the Soviet delegation included any high‐ranking military officers.

Western diplomats who had expected the move interpreted it as an indication of some Soviet nervousness about the course of the war and its political ramifications, following the overwhelming vote in the United Nations General Assembly in favor of an immediate cease‐fire, which Pakistan has accepted and India has rejected.

In the last two days, Western diplomats have interpreted public commentaries in the Soviet press as indicating some Soviet misgivings about the reactions abroad to the Indian military campaign. It was understood that initially the Indian Government had been reluctant to receive Soviet delegation in New Delhi during the hostilities.

The dispatch of a Soviet delegation as well as the expected arrival here of a high‐level Indian delegation led by a former Ambassador, D. O. Dhar. were seen as an indication that both the war and the political maneuvering had reached a decisive stage that required direct high‐level coordination between Moscow and New Delhi.

According to diplomats familiar with Soviet‐Indian strategy, the two powers had originally expected that Indian forces would gain effective control over East Pakistan this weekend. This suggests that the final assaults on the city of Dacca are either imminent or that the Soviet‐Indian timetable has proved too ambitious.

In either event, it was suggested here, the situation has reached a sufficiently critical juncture for Moscow to override New Delhi's embarrassment over having a high‐level Soviet delegation arrive in the midst of the war and to insist upon having its own top‐level observers on the scene.
