They didnt invent the astrolabe!
He is so deep into the walk that all that is left to him is the walk itself. He lost all his hopes, his dreams and likely had before the walk even started. The walk was a giant death wish and he was going on till he met it.
Step 1 of the Anaconda plan was to completely blockade all ports that were in any way related to the southern territories. They wanted to prevent them from getting help from outsider countries such as European countries which were willing to help the Southerners at the time. By blocking all ports, they would prevent them from ever leaving the territory. This step was conducted by the Navy.
Step 2 was about cutting it off from help from the Americas. It was about a continental blockade where the southerners would be surrounded from all sides, from Northern states in the north, to northern blockades in the East and West. They would occupy and block things like railroads or similar roads and would prevent anything from getting in or going out of the territory.<span />
This is Hemingway's belief that issues should be dealt with stoically and heroically. This can be seen in The Old Man and the Sea in the way the man never gives up and fights the Fish with all that he's got.
Hope it helps! :-)
