On December 14, 1893, Albert Willis arrived in Honolulu aboard the USRC Corwin unannounced, bringing an anticipation of an American invasion to restore the monarchy. With the hysteria of a military assault, he stimulated fears by staging a mock invasion with the USS Adams and USS Philadelphia, directing their guns toward the capital. Willis' goal was to maintain fear of the United States to pressure the Provisional Government into forfeiting the island back to the queen or at least to maintain a US invasion as a possible reality, carrying out this to the limit of the Navy remaining officially neutral. He stated there were more than 1,000 men of military age in the city the Provisional Government was arming. Willis ordered Rear AdmiralJohn Irwin to organize a landing operation using troops on the two American ships. He made no attempt to conceal preparations of the operation, as men readied equipment on deck. The next shipment of mail, news, and information was yet to arrive aboard the Alameda, so until then the public was uninformed of the relations between Hawaii and the U.S. Sanford B. Dole, President of Hawaii attempted to quell the anxiety by assuring the public there would be no invasion. On January 3, 1894 public anxiety became critical which gave the incident its name, the “Black Week”. As the anticipation of a conflict intensified in Honolulu Irwin became concerned for American citizens and property in the city, considering he may actually have to land troops to protect them if violence erupted in retaliation for the crisis. The Commanders of the Japanese HIJMS Naniwa and the British HMS Champion asked to join the landing operation, like Irwin, to protect lives and property of their respective nationalities. On January 11, 1894, Willis revealed to Dole the invasion to be a hoax.

Though Willis did not restore the monarchy, he was able to incite doubt in the Hawaiian public over the Provisional Government and communicate that the US was capable of going to war with them. This was one of the factors resulting in the formation of the Republic of Hawaii. To Cleveland this was an improvement; avoiding annexation left the potential to restore the monarchy and was more favorable in keeping Hawaii an independent country than as a territory of the United States.
