TELEMACHUS
The signal was raised using Sir Home Popham's Telegraphic Code (1800), that was adopted by the Navy in 1803. The signal required twelve 'lifts' as shown on the left (the word 'duty' was not in the code book and had to be spelled out), and its transmission took some 4 minutes. The signalling team, led by Signal Lieutenant Pasco, would have consisted of up to 4 midshipmen and 6 seamen.
