This is one of the problems with starting a war with the assumption that you’ll achieve an overwhelming victory in a matter of weeks. At this point the only practical options for resupplying the Lincoln are to supply it by sea (involves tying a defenseless ship to the side of it and moving both in a straight line for a few hours) or to move it where the food is and hope it doesn’t impact their blockade plan too badly.

I sometimes see people making fun of the book “The Art of War” because it’s mostly stuff like “you can’t win a war if you aren’t able to feed your troops” that should be obvious to anybody who’s competent. Situations like this show that it’s still useful because sometimes you have leaders that need very simple concepts to be explained to them.
