How did logistics allow the north to defeat the south?

the north had a bigger population due to the fact that the north had industries that supplied people with jobs, that meant they had a bigger army than the south had. the north also had a navy so they could blockade the south.  They also had railroads to transport supplies quicker to the soldiers such as foo and water, medicine, and ammunition. 

How is this a question? ?

Acase involving the laws of a single state.
