Britain and Portugal sign a secret Treaty of Windsor. By the terms
of this agreement, Britain promises to protect Portugal's hold over
its colonies, while the Portuguese promise to aid the British in
their war against the Boers by obstructing the passage of munitions
from Delagoa Bay to the Transvaal.
