The Spanish-Americas War (Great Rapprochement)

Beginning in 1898 with the sinking of the CSS Savannah in Havana harbor, and 3 months later the bombing of the USS Baltimore in Mirs bay in Hong Kong, the estranged sibling states of the Confederate States of America and the United States of America were brought to war against Spain.

War
In response to the bombing in Hong Kong, and in part because of the longstanding naval rivalry between the United Kingdom and Spain, the British offered resupply and support near any British colony for the duration of the war.

Aftermath
North America following the Spanish-Americas War

Within a matter of months, the CSA had secured Cuba and Porto Rico as their territories, and the USA the Philippines and Guam. A full peace was negotiated in the end months of 1898, and ratified by the congresses of the Confederate States and the United States in January and February respectively.

This war did little to ease the tensions between the CSA and the USA, and served only to hone the military apparatuses of these two feuding nations. The CSA became embittered against the British because of their support of the United States, and diplomatic tensions increased between the two nations.
