A hand-sewn silk, Blue Ensign (post-1801 design). The linen reinforcement at the hoist and the rope for hoisting is in place. The size indicates that it was probably used as a boat ensign. The ensign was handed down through the Forbes-Robertson family with a diary kept by Lieutenant J. Robertson from 1798-1835 (now in the Huntington Library, California).

The ensign was said by the donor to have belonged to HMS 'Tigre' 1795 (John Robertson was a lieutenant in this ship in 1807). 'Tigre' commanded by Benjamin Hallowell took part in Nelson's pursuit of the French Fleet to the West Indies but was not present at the battle of Trafalgar. Hallowell commanded the naval part of the expedition to Alexandria in 1807. 'Tigre's' commission ended in 1811 with his promotion.
