Stalin and Purim

According to the story I've heard, Joseph Stalin (may his name be blotted) died on Purim day 1953 (5713). From what I can see, that is not precise but has a kernel of truth.

Stalin died on March 5, 1953 from what seems to have been a plot to poison him (link). However, Purim in that year was on March 1, 1953 (link, link). Which, for those who can do the math, means that he did not die on Purim. However, on March 1 he collapsed and eventually died four days later. So there is some truth to his being defeated on Purim.
