FV,
As Cheezer says, we were recipients of Marshall Aid. We received $962 million. I'm not certain that we spent it on India, though - India had become independent before the aid package was authorised.
From what I recall, the prime cause of the 1946/47 probelms (other than the snow...) was incomptence - there was enough fuel to keep the power stations (and therefore industry) going, but the government failed to move the fuel to the power stations (failing to appreciate that it was a tad awkard to transport the fuel once the roads were under several inches of snow).
