Answer:In Chapter 8, Frederick pays for timber with forged banknotes, then has his men attack Animal Farm. When Frederick and his men arrive with their guns, the animals are unable to repel the attack and hide inside the barn to avoid being shot. While the animals are inside the barn, they watch as Frederick's men drill a hole at the base of the windmill. The men then fill the hole with explosives and blast the windmill to pieces. Immediately, the animals become enraged at the destruction of the windmill and overrun Frederick's men. Several animals die during the battle, and nearly every animal is wounded. Despite successfully repelling the attack, the windmill no longer exists. The force of the explosion was so great that the stones were blown to small pieces, and there are no remains of the former windmill.
