by John Marshall, Royal Naval Biography — Clavell… (1823)
“ Captain Clavell was at Corfu when the Russian governor received instructions to give that island up to France, agreeably to an article in the treaty of Tilsit, but of which the British Minister, Speridion Foresti, Esq. was kept in profound ignorance until the arrival of part of the enemy’s troops intended for its future garrison. The Weazle was then returning thither with some important despatches from the senior officer off Venice, and but for a fortunate calm, at some distance from the harbour, she would in all probability have been captured. ”
