But what Arthur was sure of was that what Garibaldi wanted to hear was definitely not this, but rather the Battle of Navarino in October 1827, where Codrington led his forces to annihilate the Ottoman Empire's navy.
After this battle, the Ottoman Empire's maritime power was utterly destroyed, and the Greeks rejoiced, hailing Codrington as a hero. Unfortunately, this battle was purely a military accident.
Because the British Foreign Office did not want the Ottoman Empire to be too severely damaged, lest they were unable to continue keeping the Russians out of the Mediterranean Sea.
The main reason Britain intervened in Greece was due to domestic public opinion pressure and the wish to prevent an independent Greece from leaning towards France or Russia.
Had it not been for the Ottomans killing the messenger sent by Codrington, which enraged this veteran of the Royal Navy, Codrington would most likely have strictly adhered to the Foreign Office's orders to absolutely not engage.
