Quest to getting my Slant six to turn over

The battery is most certainly 100% toast but i figured that if it was being helped with a jump it would be able to do something. I forgot to mention it was just donor power from another car.
The lights don't dim when trying to crank but the lights themselves are in poor shape to begin with. Only the gear position on the steering column has enough light to be readable. Thank god the starter is actually reachable by hand, if it is bad i won't have to dissect the engine bay to reach it.

I suppose the first thing to do is actually spin the engine. I didn't even think of that one.
