SM U-79 was one of the 329 submarines serving in the Imperial German Navy (Imperial German Navy) in World War I. U-79 was engaged in the combat in the First Battle of the Atlantic.

After the war she was transferred to the French Navy, in which she served as Victor Réveille.

Imperial German Navy

SM U-79 was commissioned by Kaptlt. Jess, who was replaced by Kaptlt. Rohrbeck in January 1917.^[11] Rohrbeck would be replaced by Kaptlt. Stevogt.^[12] U-79 came off the stocks at Hamburg (Vulcan) in 1916, and joined the Kiel School, where she is known to have been in July, and left Kiel for Wilhelmshaven about the end of July to join the 1st Half Flotilla.

Between 6 and 26 August 1916, she laid 34 mines off the south coast of Ireland.^[12] She fired on a special service vessel north-west of Ireland on the night{{Clarify|date=December 2009|19-20 Aug or 18-19 Aug?}} of 19 August; the torpedo missed.^[12] In the period 26 September to 14 October 1916, she laid mines in the Firth of Clyde.

Patrolling off Portugal, via the English Channel, between 21 December 1916 and 28 January 1917, she sank eight steamers and one sailing ship, as well as capturing the Norwegian steamer Nanna on 24 January. On her return journey, by way of the Irish Channel,^[12] U-79 compelled Nanna to take her under tow to the Danish coast,^[12] likely as a result of engine damage she reported 26 January.^[12]

On 1 April 1917, she departed to lay mines in Inishtrahull Sound, but could not complete her task due to engine trouble, and returned on 21 April.^[12] She made three more minelaying patrols in 1917, one off the Butt of Lewis between 6 June and 4 July;^[12] one in Rathlin Sound and off Inishtrahull Island,^[12] between 12 September and 15 October, during which she also sank the armoured cruiser {{HMS|Drake|1901|6}} off Rathlin Island, 11 October, avoiding Heligoland Bight (per a 10 October general order)^[13] on her return; and one between 17 and 20 December, off the Dutch coast, transiting Heligoland Bight inbound and outbound on this occasion.^[12] She departed for a repeat of this mission 1 January 1918, but was forced to return 5 January due to compass trouble.^[12]

She carried out training off Augustenhof Lighthouse, in the Baltic Sea, from 5 to 9 February, before departing on her next patrol,^[14] to lay mines off the Netherlands, returning 19 February, again avoiding Heligoland.^[12]

Summary of raiding history

French Navy

After she surrendered, U-79 was transferred to France as a war prize. She served in the French Navy with the name Victor Réveille.

On 23 November 1923, Victor Réveille ran aground at Boulogne, Pas de Calais, France.^[18] She was refloated, repaired, and returned to service.
