What propaganda is spread about Snowball's wound in the Battlenof the Cowshed?

In April, Animal Farm was proclaimed a Republic, and it became necessary to elect a President. There was only one candidate, Napoleon, who was elected unanimously. On the same day it was given out that fresh documents had been discovered which revealed further details about Snowball's complicity with Jones. It now appeared that Snowball had not, as the animals had previously imagined, merely attempted to lose the Battle of the Cowshed by means of a stratagem, but had been openly fighting on Jones's side. In fact, it was he who had actually been the leader of the

human forces, and had charged into battle with the words "Long live Humanity!" on his lips. The wounds on Snowball's back, which a few of the animals still remembered to have seen, had been inflicted by Napoleon's teeth.
