RFA Slavol:
The RFA Slavol was built as a 2,623 Grt. Fleet Oiler for the British Admiralty (Royal Fleet Auxiliary) by Greencock & Grangemouth Dockyard Co., Ltd., Greencock. The ship was launched 21 April 1917 and completed 01 November 1917. She was 320.1 feet in length, 41.6 feet in beam, and 23 feet in draught. Propulsion was provided by three 200-PSI Scottish Boilers and a single triple expansion engine (cylinders 26", 42.5", and 70") provided by Richardsns, Westgarth & Co. Ltd., Hartlepoole, which generated 541 NHP connected to a single screw for cruising speed of 14 knots. The ship carries 300 tons of fuel oil for her own consumption and had a normal compliment of 39 officers and crew.
          Sister ships of the "RFA Slavol", the "RFA Prestol" (R) and "RFA Belgol" (L).
This ship class was identifiable by the two masts forward and aft, and the funnel placed amidships.
                   Most of this class of ship would later have the aft mast removed.
The ship's service history during WW1 has not been located to date. However, at the end of the First World War, the ship may have been sent to Estonia to provide fuel and coal to the Royal Navy fleet located there.

The next we hear of the Slavol is on 20 June 1928 when the 20 Royal Navy Marines are ordered to the ship which was then despatched from Trincomalee, Sri Lanka, to assist the passenger liner S.S. Jervis Bay. The ship had been enroute to Colombo, Sri Lanka when approximately 8 stowaways onboard seized control of the ship near the Cocos Islands and threatened to set the ship on fire. The Slavol was sent to intercept the Jervis Bay and place the marines onboard. The Slavol, after had having some difficulty located the ship, finally intercepted the Jervis Bay and the marines were placed onboard. The stowaways, in their tropical shorts, made a show of bravado and laughed at the Royal Marines, but were otherwise well behaved. They were arrested and upon arrival at Colombo, were tried, found guilty, and served 5 and a half months in jail.
During the Second World War the RFA Slavol is documented as having been part of two convoys. The first, Convoy BN.9, consisted of 22 ships and 6 escorts and departed Aden on 18 November 1940. The Slavol is listed as having been part of Convoy BN.9A and not part of the original convoy. So it must be assumed that the ship joined the convoy enroute, arriving at Suez on 25 November.
The second convoy, Convoy TA.27 departed Alexandria, Egypt On 26 March 1942 destined for Tobruk. The Slavol was laden with a cargo of fuel oil under the escort of the HMS Jaguar and the Greek Destroyer Queen Olga.

Two versions concerning the sinking of the Slavol have been located:

First (From the sinking of the HMS Jaguar): During escort of HM RFA SLAVOL with Greek destroyer QUEEN OLGA, came under attack by German submarine U652 (Oblt. Herwig Collmann) whilst rescuing survivors from the SLAVOL, which had been set on fire after being torpedoed by U652, and was herself hit by two torpedoes from same submarine in position north-east of Sollum (31.53N 26.18N.). Sank immediately with only 53 survivors who were rescued by HM Whaler KLO (SANF). 193 of ship's company lost their lives.

AND....., At 02.27 hours on 26 Mar, 1942, HMS Jaguar (F 34) (LCDR L.R.K. Tyrwhitt, DSO, DSC, RN) was attacked by U-652 (Oblt. Georg-Werner Fraatz) with a spread of four torpedoes north-east of Sollum. Two of the torpedoes struck in the bow, the ship caught fire and sank in a short time. Three officers and 190 ratings were lost. Eight officers and 45 ratings were picked up by HMS Klo and taken to Tobruk. The destroyer had been part of the escort for the tanker RFA Slavol, which was sunk some hours later by U-205 (Reschke).

Second: At 05.10 hours on 26 Mar, 1942, the escorted Slavol (Master George Sydney Perry) was hit by one stern torpedo from U-205 and sank within five minutes off Sidi Barrani, Egypt at location 32.01N/25.55E. The ship had been missed by a spread of four bow torpedoes three minutes earlier. 36 crew members were lost. The master and 19 crew members were picked up by RHS Vasillisa Olga (D 15) and landed at Alexandria. The fleet oiler was enroute to Tobruk to bring fuel for the 5th Destroyer Flotilla.

These two versions of the sinkings of the Jaguar and the Slavol do not match. Need some additional research on this one........
