"Important from New-Orleans: Reported Attack on the National Fleet – 3"

This is the Head of the Passes attack on the Union blockading fleet, October 12, 1861, a Confederate victory, some damage to ships but no reported casualties.
By my count it was the war's 56the engagement:

Louisiana 1861 Engagements

Date	Engagement	Military Units	Losses	Victor
Oct 12	Head of the Passas, Louisiana	Union Navy Blockading Squadron , (Pope 5-ships) & Confederate "Mosquito Fleet" (Hollins 10 boats & fire rafts)	none 4 ships damaged	CSA (Union surprised routed)

There were no major engagements between the Head of the Passes in Louisiana, Oct 12 and three significant battles on the same day later “next week”.
