Didn’t Jefferson declare war on the Barbary pirates? Going from memory here...
Don’t know, my knowledge of that part of our history is fuzzy, however, it really interests me and I intend to rectify that deficiency!
I do not believe he did. My recollection is something like ... he sent the Navy and Marines during a Congressional recess. Then reported to them later.
No. The Barbary Pirates was the second undeclared US war.
The Quasi War with France was the first undeclared US war.
