The battle took place in the Rilax bay north of the Hanko Peninsula, next to the Riilahti Manor. In Sweden and Finland, the battle is therefore known as the Battle of Rilax (Finnish Riilahti). It is also known in some sources as the battle of Ahvenanmaa, the Finnish name of Åland which Russia seized after its victory.

The Russian Tsar Peter I had begun his offensive in Finland in the spring of 1713. The Russian armies quickly advanced all the way to Turku on the southwestern coast of Finland, and with Russian victory in the Battle of Storkyro on 19 February 1714, left southern Finland fully in Russian control. The Russian governor in Finland, Prince Mikhail Galitzine, with his headquarters in Turku, was unable to receive support by sea, which was then far more important than land based support as Swedish battle fleet under Admiral Gustav Wattrang had started blockading the coastal sea route past Hanko Peninsula already on 24 April. While it also blockaded the Russian supply route the blockade also prevented the Russian coastal fleet from reaching Sweden and raiding the Swedish coast. First Russian transports left from Helsingfors in early May but had to stop east of Hangö to Ekenäs from where the supplies needed to be hauled overland. Russian attempts to provide ships to west of Hangö ended when newly formed Swedish coastal squadron led by Captain Anton Wrangel intercepted the Russian supply ships south of Turku on 10 May and in one sided engagement sunk most of them while the rest were scattered. Admiral Apraksin's fleet was sent from its base at Kronstadt by the Tsar to open these service lines.

When the 80 ship strong Russian galley fleet arrived near the peninsula on 29 June 1714 they were met by a strong Swedish naval fleet consisting of 16 ships of the line and 7 smaller ships under the command of Admiral Wattrang. Apraksin decided to withdraw his ships farther away to the eastern side of the peninsula and call for reinforcements while he waited for the further 20 galleys to arrive from Helsingfors where they had been over the winter. The majority of the troops in Turku were moved according to his request to the peninsula. A plea for help was also sent to the Tsar, who was with the rest of the Baltic Fleet in Reval (now Tallinn). Admiral Apraksin specifically let the Tsar know that he should come personally to lead the attack. Russian battle fleet of 10 ships of the line and 6 frigates was originally intended to participate to the breakthrough attempt at Hangö but upon inspecting the fleet Tsar found it ill prepared for battle and abandoned the use of the battlefleet. Further he ordered that fleet should not engage unless it would have clear superiority in artillery (3:2). Peter I reached the Russian coastal fleet on 20 July.

After the breakthrough, Russian galleys gradually pushed Ehrenskiöld's detachment back, causing him to order his vessels to form a defensive line between two islands. One of the skerry boats was scuttled in order to narrow down the area where the fight would take place with obstacles. The largest Swedish ship, the pram Elefanten, was positioned broadside on to the approaching Russian vessels. Three galleys were stationed end on on each side, with the boats behind the line. After Ehrenskiöld refused to surrender, the Russian fleet attacked on 27 July 1714 at 14:00. According to Swedish sources, the Russian galleys, commanded by the Tsar, attacked twice (first with 35 galleys, then with 80 galleys), but were thrown back both times. The third time, when attacking with reinforcements and a combined force of about 95 galleys, the Russians managed to reach the Swedish ships and engage in close quarters combat, where superior Russian numbers could be used to their advantage. Russians managed to board the Swedish galley farthest left in the line, the Tranan, which capsized and sank, creating a hole into the Swedish line. Russian galleys made use of the opening and were quickly able to start boarding the rest of the Swedish ships. Fighting lasted for three hours as the Swedes defended all of their ships. The fighting ended with the capture of Elefanten, where Admiral Ehrenskiöld himself was taken prisoner of war on the deck of his own flagship. The Swedish description of the battle is not supported by Russian documents of the time and was proven incorrect in many aspects by the Russian historian Prof. Paul A. Krotov in 1996. In his research based on a large number of Russian and foreign archive documents related to the battle and dating back to the 18th century, Krotov demonstrates that the Russian fleet launched only one massive attack on the Swedish position. The overall number of Russian galleys was slightly smaller than reported: 98. Krotov also discovered numerous sources mentioning that over the course of the battle 4 Russian “scampavia” gunboats attacked the Swedish ships from the rear. Russian galleys were designed differently from Swedish galleys. While carrying generally inferior artillery at two 6 pounder guns per galley, they had a larger crew complement, usually close to 200 men per galley. The Russians substantially outnumbered the Swedish, according to some Swedish sources 15 to one. Russian numbers in the battle were such that there wasn't enough room for all Russian vessels to fight at once, so only 23 vessels engaged.

While the defeat of the small Swedish squadron didn't have much consequences, the fact that over 70 Russian galleys had run the Swedish blockade at Hangö and reached the Archipelago Sea had. The Swedish battlefleet which had been blockading Hanko Peninsula was quickly moved west of Åland to protect Sweden against raids by Russian galleys. This also opened the coastal seaway for the Russian transports. A Russian galley fleet under Admiral Apraksin started from Rilax on 1 August to sail towards Åbo from where he continued already on 5 August towards Åland. By 8 August Apraksin reached the east coast of Åland triggering Swedish withdrawal from the islands. On 13 August whole of Åland was under Russian control. As the Swedish battlefleet prevented Apraksin from reaching Sweden the galleys were diverted to support the Russian army fighting along the coast of Gulf of Bothnia with small squadron plundering and razing the Swedish town of Umeå on 18 September. The Presence of the Russian galley fleet on Bay of Bothnia forced the remnants of the Swedish army in Finland to hastily withdraw to Torne River to avoid getting encircled.

Russians later embellished the description of the battle of Gangut by reclassifying the oared flat bottomed gun pram Elefanten into a full sailing frigate. The battle was the first major victory of the Russian galley fleet, and is occasionally as such compared by Russians with the Battle of Poltava. The victory is even nowadays celebrated by the Russian Navy; Russia's Navy Day holiday takes place on the last Sunday of July in commemoration of the battle. The Imperial Navy traditionally had one vessel named Gangut, with its first series of Dreadnought battleships named the Gangut class. The first monument to commemorate the Russian Navy, a wooden cross, was erected on the site in 1869 by Rear Admiral Rimsky Korsakov, brother of the famous composer, Nikolai Rimsky Korsakov. The wooden cross was replaced by a more permanent stone cross in 1870 by the order of Tsar Alexander II. The memorial is at Riilahti manor in Bromarv, Raseborg, Finland, which is owned by the Aminoff family.
