Who wanted the windmill specifically for milling corn?

Napoleon wanted the windmill specifically for milling corn as part of his broader vision for the farm's productivity and self-sufficiency. He believed that by building the windmill, the farm could harness wind power to improve efficiency in processing crops, particularly corn, which was a significant agricultural product. This goal aligned with his ambitions to elevate the farm's economy and strengthen his leadership position.

The other characters had different focuses and motivations that did not center on the windmill specifically for milling corn. Snowball initially promoted the idea of the windmill as a way to enhance productivity and facilitate the farm's technological advancement, but he had broader intentions and was quickly ousted by Napoleon. Boxer, the loyal workhorse, was dedicated to the labor needed for the windmill but did not express specific desires regarding its purpose. Old Major, the intellectual pig who inspired the revolution, laid the philosophical groundwork for the rebellion but did not articulate specific plans like the windmill during his time. Thus, it is Napoleon's vision and strategic prioritization that clearly identifies him as the character who wanted the windmill for milling corn.
