In what year did the Attack on Algiers take place?

The Attack on Algiers took place in 1816, which is established as a significant event during a period when the United States was seeking to put a stop to the Barbary pirates' raids on American shipping. This military action was part of a broader confrontation with North African states that had been holding American vessels and their crews for ransom. The decision to launch this attack represented a crucial moment in asserting American naval power and highlighted the shift in U.S. foreign policy towards a more proactive stance against piracy on the high seas. The other years listed do not coincide with this event, making 1816 the correct and relevant answer.
