In Animal Farm, how does the battle of windmill affect the animals?

At first,
the animals are devastated. But afterand the pigs work their magic, the animals forget and even
begin to celebrate. 

This is the second time they have built the windmill. It
was first lost in a storm.is counting on the money from wood he has sold to Frederick, but
Frederick gives him fake bank notes, essentially stealing the wood. The money was to be for the
machinery in the windmill. Then Frederick and his men attack and destroy the windmill. Napoleon
asks Pilkington for help in fighting them off but Pilkington refuses. Although they are able to
drive Frederick and his men away, this is a devastating defeat. (In the historical parallel, the
Animals/Russians are able to drive off the Humans/Germans, but they suffer much destruction and
many casualties.) 

However, Squealer turns thisvictory into a grand victory.
Squealer is an artist of propaganda. When the commandments need changed to suit the pigs' newest
desires, he makes subtle changes so that the animals might not know the difference. He is able
to spin arguments around to suit the pigs' latest agenda. And he does this with the Battle of
the Windmill as well. The losses are great. The loss of the windmill is huge because it took so
long to build and because it was the second time building it.is incredulous when Squealer
proclaims it a victory. But as he and the other pigs celebrate, the weary animals come to
believe that it actually has been a victory. Such is the power of propaganda. Even the theft of
the wood is forgotten. 

Two whole days were given over to
celebrations. There were songs, speeches, and more firing of the gun, and a special gift of an
apple was bestowed on every animal, with two ounces of corn for each bird and three biscuits for
each dog. It was announced that the battle would be called the Battle of the Windmill, and that
Napoleon had created a new decoration, the Order of the Green Banner, which he had conferred
upon himself. In the general rejoicings the unfortunate affair of the banknotes was
forgotten.
