Rio de Janeiro Affair

The Rio de Janeiro Affair refers to a series of incidents during the Brazilian Naval Revolt in January 1894. Following three attacks on American merchant ships in the harbour of Rio de Janeiro, a bloodless naval engagement occurred between a United States Navy warship and an ironclad of Rear Admiral Saldanha da Gama's rebel fleet. Ultimately the Americans completed their objective, and Gama offered to surrender his fleet to the Americans, but the offer was never pursued..

Affair

The incidents which led to the short engagement began on 21 January 1894, when the 586 ton American bark SS ''Julia Rollins'' was fired on with rifles from a fort on Cobras Island, while heading to Gamboa. Brazilian fire was heavy though nobody was harmed; the American crewmen were forced to take cover and maneuver their ship out of the fort's range, where they laid anchor. The Brazilian rebels then opened fire again, but this time with the guns of the ironclad cruisers '' Trajano'' and ''Guanabara''. ''Julia Rollins'' moved once more until finding a safe anchorage, then a boat with a few sailors was lowered and sent to inform admiral Andrew E. K. Benham, who was in command of three cruisers at Rio de Janeiro with orders to protect American interests and observe the rebel blockade of the city. On 26 January, another incident occurred when the bark ''Agate'' was fired at with rifles and naval guns from Cobras Island and the rebel cruisers. Again nobody was hurt, but admiral Benham, who was busy communicating with Gama, warned him not to attack American vessels. USS ''Detroit'', under commander Willard H. Brownson, was one of the modern cruisers in Benham's squadron. The other two were the USS ''San Francisco'' and USS ''Newark''. Admiral Saldanha da Gama's fleet of twenty-four ships was much stronger, as most of the rebel navy was stationed at Rio de Janeiro, though only the ''Trajano'', the cruiser ''Guanabara'' and the gunboat ''Liberdade'' were directly involved. The 1,400 ton ''Trajano'' was armed with twelve guns and the much larger 2,200 ton ''Guanabara'' mounted eight. ''Liberdade'' was only 250 tons but armed with eight guns. It was Gama's flagship and patrolled back and forth between the two cruisers and the main fleet. Brazilian commanders expected a battle against the American squadron so men from other ships were used to reinforce the ''Trajano'' and the ''Guanabara''..

The affair climaxed on 29 January when Benham ordered commander Brownson to escort the American merchantmen into the wharves, where their cargoes would be unloaded, and to attack the first Brazilian ship to open fire. So at 6:00 am the ''Detroit'' headed in, followed by the ''Julia Rollins'', the ''Agate'' and the barks ''Amy'' and ''Good News''. The ''Detroit'' was cleared for action and at 6:20 the crew was at battle stations with guns loaded. But just then, while sailing between Cobras and Enchadas Island, lookouts observed two or three Brazilian auxiliary cruisers which were beginning a bombardment of the federal shore batteries near Santa Barbara Island. Commander Brownson decided to wait for the engagement to end so he did not violate neutrality, and as soon as the armed tugs hauled off the American ships were underway. The ''Trajano'' and ''Guanabara'' were not far away, the two cruisers were moored to a buoy in line of battle, and Admiral Gama's flagship was nowhere in sight. By 7:00 am, ''Detroit'' and her escortees were within gun range of the rebels and at about that time the ''Trajano'' fired a warning shot over the ''Amy''s bow which temporarily stopped her. In order to get the ships moving, Commander Brownson had to assure the merchantmen that he would protect them if there was any more fire. An attack came a few minutes later; at 7:04 the ''Amy'' received a round from the ''Trajano''s naval musket. Immediately ''Detroit'' returned fire with one of her guns and a shot hit the ''Trajano''s stern about two or three feet from the starboard bow, causing light damage. Brownson then hailed the Brazilians, who were less than sixty yards away, and the commander declared that "''If you fire again l will return the fire, and if you persist in firing I will sink you'. However, ''Trajano''s crew opened fire again with a full broadside from the starboard battery; one near miss went over the ''Detroit'' and another over the ''Amy'' but no damage was caused.

For the next several moments the ''Detroit'' maneuvered, and at 7:16 am Brownson found himself in a good position to rake the enemy vessels from 200 yards away. That morning the sea was rough, so the anchor was dropped and preparations were made to slip the cable if necessary. The American barks were directed to continue on to the wharves. At 7:32 am the ''Trajano'' fired another broadside at the ''Amy''; all shots missed. USS ''Detroit'' responded and a second round struck the ''Trajano'' under the counter, near her sternpost. Following this the rebels ceased firing and the engagement was over, after about a half an hour. Admiral Gama only found out that there had been an exchange of fire when he anchored the ''Liberdade'' and two of the tugs near the ''Guanabara''. Captain Brownson sent an officer aboard the ''Liberdade'' to ensure a ceasefire. Gama said that he had not ordered the attacks on the American barks, and that only blank rounds had been used during the first incidents in order to scare off the merchants and not actually harm them; however minor damage from rifle fire to the ''Agate'' and the ''Julia Rollins'' proved otherwise. Gama also offered to surrender his fleet to admiral Benham, but the offer was not pursued. American reports make no indication of casualties on either side and the affair did not go any further. In the end, ''Detroit'' successfully reopened Rio de Janeiro to American commerce, and Brownson's bold actions are credited with preventing any more attacks on United States flagged ships during the revolt, which ended in March 1894. The captain became known for the engagement, and newspapers across the United States reported the story.
