From September 1918 to May 1919, Commodore David Norris RN had built up a flotilla of armed merchant cruisers (AMC) with which, by May 1919, he had wrested control of the Caspian Sea from the Soviet Navy.
When Britain withdrew its forces from the area in August 1919, eight AMCs of the Caspian Flotilla were handed over to General Denikin's Volunteer Army.
[1] But in March 1920, advances by the Soviet Red Army threatened the flotilla's base of Petrovsk (now Makhachkala) and General Erdeli (whom Denikin had appointed Russian Governor of Dagestan)[2] was compelled to evacuate his forces by sea.
With no other safe port to go to, the flotilla sailed to Enzeli, on the North Persian coast, where a detachment of Norperforce was stationed under the command of General Bateman-Champain.
He had previously advised the Admiralty in January, about a proposed earlier mission, that it should not proceed unless Baku was re-occupied and the safety of the Batum-Baku railway assured.
[citation needed] The party sailed from Constantinople in HMS Gardenia, across the Black Sea, arriving at the British-occupied Georgian port of Batum on 21 April, where they awaited further orders.
After the arrival of de Robeck next day, and on receiving the report of Commander Luke (the chief commissioner at Tiflis), they were allowed to depart by train on 23 April.
[citation needed] After a journey of four days, they arrived at Baku on 27 April at about 16.00, to be greeted with the news that the Bolshevik 11th Army had crossed the northern frontier of Azerbaijan at 01.00 that same morning.
The cells were only opened for half an hour each evening, when exercise was allowed in a small courtyard, in which there was a tap and trough - the only washing facilities provided.
Commander Fraser managed to persuade an interpreter to contact the Dutch Consul, and requested him to look after the safety of Hewelcke and to supply the party with food.
Despite British support for the White Russians against them, the Soviets were desperate to acquire much needed goods and, pragmatically, put their animosity towards Britain to one side for the duration, and negotiations began in early June.
They will be sent to Tiflis, where-to the people's commissary for Foreign Affairs of the Azerbaijan Republic has departed, there personally to negotiate the details of the transfer of the prisoners.
They reached Akstafa, a small town five miles from the frontier at 14.00 on the 6th, and waited for a day amidst snow and bad weather, during which time the remainder of their gear was searched again.
[7] Before allowing the train to proceed to Tiflis, the Georgian Government, who were acting as intermediaries, were waiting for confirmation that the 300 Russian exchange prisoners from Egypt and Constantinople had arrived at the Black Sea port of Odessa, Ukraine.
[8] Twenty four years later, Admiral Fraser, as commander-in-chief of the Home Fleet, was awarded the Order of Suvorov 1st Class by the Soviet Union for his part in the sinking of the Scharnhorst in the Battle of the North Cape.
