six 2 to 4-pounder guns. In 1635, the East India Company established a shipyard at Surat, where they built four pinnaces and a few larger vessels to supplement their fleet. In 1686, with most of the English commerce moving to Bombay, the force was renamed the "Bombay Marine". This force fought the Marathas and the Sidis and took part in the Anglo-Burmese Wars. While it recruited Indian sailors extensively, it had no Indian commissioned officers. Commodore William James was appointed to command the Marine in 1751. On 2 April 1755, commanding the Bombay Marine's ship Protector, he attacked the Maratha fortress of Tulaji Angre at Severndroog between Bombay and Goa. James had instructions only to blockade the stronghold, but he was able to get close enough to bombard and destroy it. In February 1756, the Marine supported the capture of Gheriah (Vijaydurg Fort) by Robert Clive and Admiral Watson, and was active in skirmishes against the French, helping to consolidate the British position in India. In 1809, a fleet of 12 ships of the Marine bombarded the city of Ras al-Khaimah, a pirate stronghold, in an unsuccessful attempt to quell Arab piracy. A subsequent mission in 1819 with 11 vessels proved successful in blockading the city for four days, after which the tribal chieftain surrendered. In 1829, the "Bombay Marine" received the additional name of "Corps", and also received its first steam-powered vessel, . Steaming from Bombay on 20 March 1830, Hugh Lindsay reached Suez after 21 days under steam (plus coaling stops at Aden, Mocha, and Jeddah), at an average speed of six knots. Between 1830 and 1854 the Indian Navy was responsible for maintaining mail service on the Bombay and Suez leg of the "overland route" (England–Alexandria, Alexandria–Suez overland, and Suez–Bombay). 1830–1858 In 1830, the Bombay Marine was renamed the "Indian Navy". The British capture of Aden in the Aden Expedition increased its commitments, leading to the creation of the "Indus Flotilla". The Navy then took part in the First Opium War of 1840. By 1845, the Indian Navy had completed the conversion from sail to steam. In 1848, an Indian Navy contingent of 100 ratings and seven officers took part in the Siege of Multan during the Anglo-Sikh War. In 1852, at the outset of the Second Anglo-Burmese War, ships of Her Majesty's Indian Navy joined a Royal Navy force under the command of Admiral Charles Austen
