In 1758, British success elsewhere had not yet produced reliable control of the waters off Brest. Anson's squadron could remain at sea for only about six weeks because of scurvy and victualling problems, although it did receive supplies from transports on one occasion. Saunders also failed to intercept ships entering or leaving the port that October. French preparations for an invasion then made those gaps intolerable to British ministers. Hawke's later arrangements addressed weaknesses that had already been demonstrated in service.

Scurvy and supply problems limited Anson's time at sea, while Saunders also failed to intercept French movements at Brest.
