We stumbled upon this gem of a video of Sardar Vallabhbhai Patel addressing a gathering at Calcutta Maidan on 3rd January, 1948. It provides a rare glimpse into the impeccable oratory skills of a leader. His clarity of thought, no-nonsense, straightforward approach while delivering the speech is worth listening to.
He speaks about Kashmir, Junagadh, Pakistan and the partition.
