ships were also the tokens of the vast Russian land armies that could be thrown in the scales on a number of fronts, including the northwest frontier of India; the British had long been worried about such an eventuality. In mid-July 1863, French Foreign Minister Droun de Lhuys was offering London the joint occupation of Poland by means of invasion. But the experience of the Confederate commerce raiders had graphically illustrated just how effective even a limited number of warships could be when they turned to commerce raiding, which is what the Russian naval commanders had been ordered to do in case of hostilities. The Russian admirals had also been told that, if the US and Russia were to find themselves at war with Britain and France, the Russian ships should place themselves under Lincoln's command and operate in synergy with the US Navy against the common enemies.

Navy Secretary Gideon Welles: "God Bless the Russians" Coming on the heels of the bloody Union reverse at Chickamauga, the news of the Russian fleet unleashed an immense wave of euphoria in the North.

Fires of the North in eternal communion, Blend your broad flashes with evening's bright star; God bless the Empire that loves the Great Union Strength to her people! Long life to the Czar The Russians, as Clay reported to Seward and Lincoln, were delighted in turn by the celebration of their fleets, which stayed in American waters for over six months as the Polish revolt was quelled.
