British army in North America.

In southern India, the French force was
decisively defeated at Wandewash; Pondicherry, the major French base,
surrendering to the British besiegers in 1761.
In 1762, the war broadened out, when Spain entered it on the side of
France. This did not end operations against the latter, and, in the West
Indies, the British captured Martinique, Grenada, St. Lucia, and
St. Vincent. The major effor t, however, was directed against Havana, the
principal Spanish base in the West Ind ies and their leading naval facility
in the New World. The siege force was badly affected by malaria and yel-
low fever, leading to a loss of valuable experience in the army, which was
to weaken the subsequent response to the American Rev olution; but the
British finally stormed the key fortification and the city then surrendered.
The Spaniards also had to cede Florida at the subsequent peace to regain
Cuba. As with the Americans in 1898, the British also captured Manila.
Another British force played a crucial role in thwarting the Spanish inva-
sion of Britain’s ally Portugal.
These expeditions displayed the strength of the British po sition at the
close of the war. Naval superiority gave them the ability to choose where
to direct efforts and permitted the application of strength to achieve a
local superio rity at a time of cho osing a t crucial points. The French
Empire depended on the maintenance of its major bases, but, unless the
French could threaten the British at sea, these bases could be isolated
and attacked with overwhelming force. Fortifications could prolong the
defense and force the British to resort to siege, but fortifications were only
designed to last so lon g against an effective siege; indeed they were prin-
cipally designed to force attackers to resort to a siege. The effectiveness of
British sieges could be lessened by poor leadership, inadequate resources,
especially manpower, and disease. Poor leadership and inadequate
resources, never theless, were increasingly overcome as the British devel-
oped consider able and unmatched experience in amphibious operations.
The creation of overseas naval bases, providing refitting and repair facili-
ties, helped considerably.
This was important to sust aining naval strength, which was a difficult
task, not least as a consequence of the natural decay of what were organic
working parts. The longevity of most ships of the line was about twelve to
seventeen years, longevity defined as the time between launch and the
need for at least middling repair, alt hough a complex combination of fac-
tors, beginning first with the cutting of the timber, its sto rage, the mode of
construction, weather conditions, the service of the ship, and its care
while in reserve, determined the longevity of a ship and the amount of
repair that it was likely to need. In 1749, as a result of long war service,
including damaging operations in the Caribbea n, the battle fleet in good
condition had been greatly reduced, and the dockyards could not cope
with requirements for repair and replacement. This problem was
