Atlas-bound chart with annotations. Used on 'Bellerophon', showing movements of Nelson's squadron while searching for French fleet. It probably belonged to her captain, Henry Darby.

This chart of the Mediterranean Sea was used to record ‘Bellerophon’s’ track. A manuscript note in the lower margin records: ‘At 2 [p.m. on 1 August 1798] the French fleet consisting of 13 Sail of the Line & 4 Frigates were seen at Anchor between Alexandria & Rosetta. ¼ before sunset the Action began.’

Darby in ‘Bellerophon’, a 74-gun ship, took on the French flagship, the 120-gun ‘L’Orient’ which blew up at 10 p.m. ‘Bellerophon’ suffered 49 killed and 148 wounded, including Captain Darby who received a head wound. After the battle, ‘Bellerophon’ limped to Malta and from there to Gibraltar for repairs.
