Pelham: "Perhaps DL believes that because President Lincoln himself states the inability to collect revenue as his reason for ordering the naval blockade in his proclamation of April 19, 1861.
It’s in the first paragraph:"

Sure, that was the beginning of General Scott's "Anaconda Plan", to strangle the Confederacy economically.
It came a week after Confederate military assault on Fort Sumter.

But the question on the table has nothing to do with that.
The question on the table is: did Lincoln send resupply ships to Fort Sumter, in early April, in order to protect Federal revenues from tariffs mostly collected in large Northern ports?
The obvious answer is: no, that had little or nothing to do with it.
Instead, Lincoln tried to send supplies to Fort Sumter in April for the same reason President Buchanan had tried in January -- because Union troops there needed them.

“But...but...what will become of my lost cause narrative?”

LOL

If that is the case wouldn’t Lincoln have stated that his purpose was the need to protect the Fort and its troops rather than saying it was because of the inability to collect revenues?

We should go on what he wrote in his proclamation. It was important enough to him that he leads with it in his opening paragraph.
