An Argentine force farther upriver hears of the breakthrough and scuttles its sloop before the Anglo-French ships arrive. Some accounts call this a secondary action. That label is challenged here because the vessel is destroyed without an enemy engagement, making it a consequence of the battle in this interpretation. Merchant ships subsequently pass upriver, but the hoped-for end to Argentine attempts to block navigation does not follow.

Does scuttling before an enemy arrives count as an action?
A preemptive scuttling raises a question about historical terminology, while renewed resistance limits the expedition's results.
