These sketches recently came up for auction – very interesting indeed. Clearly the artist was in Macao and possibly near Canton, in or around the time of the First Opium War (1839-1842) – certainly, as Captain John Spencer Churchill died at Macao in 1840 these sketches are slightly later. The sketch of the attack on Canton in 1840 suggests the artist was with the Navy in China – perhaps HMS Volage or HMS Hyacinth. Sadly though they remain unattributed.
