The cry has been that when war is declared, all opposition should therefore
be hushed. A sentiment more unworthy of a free country could hardly be
propagated. If the doctrine be admitted, rulers have only to declare war
and they are screened at once from scrutiny. ... In war, then, as in peace,
assert the freedom of speech and of the press. Cling to this as the bulwark
of all our rights and privileges.
-- William Ellery Channing
