The ninth, but third in order of events, in a series of ten drawings (PAF5871–PAF5874, PAF5876, PAF5880–PAF5881 and PAF5883–5885) of mainly lesser-known incidents in Nelson's career, apparently intended for a set of engravings. Pocock's own (unnumbered) description of the subject in a letter of 9 July 1810 is: 'the "Agamemnons" engagement with the "Ca Ira", within Gun Shot of a Tremendous Force and no Support near', 'Agamemnon' being on the right. For the rather complex circumstances of the commission, and Pocock's related letters, see 'View of St Eustatius with the "Boreas"' (PAF5871). A variant of this drawing of the 'Ca Ira' in action, slightly extended on the right, was formerly in the collection of Sir Bruce Ingram. Signed by the artist and dated, lower right. Exhibited: NMM Pocock exhib. (1975) no. 46.
