By now, Gálvez’s exhausted column was approaching British-held Manchac near Bayou Manchac and the Mississippi River.
Many of the soldiers still did not know the full purpose of the expedition. Gálvez had concealed Spain’s declaration of war to prevent information from reaching the British.
Near Manchac, he finally revealed the truth: Spain and Great Britain were at war—and the men before him were about to attack.
According to contemporary accounts, the troops answered with cheers.
The secret march was now an open revolution.
