In 1914–1917, Baku produced 7 million tons of oil each year, totaling 28,683,000 tons of oil , which constituted 15% of world production at the time. Germany did not trust Turkey in oil matters and transferred General Friedrich Freiherr Kress von Kressenstein from the Middle Eastern front with his troops to Georgia in order to enter Baku, through Ukraine, the Black Sea and Georgia. Great Britain, in February 1918, urgently sent General Lionel Dunsterville with troops to Baku through Anzali to block the German troops. Having studied the Caucasus from the strategic point of view, Dunsterville concluded: "Those who capture Baku, will control the sea. That's why it was necessary for us to invade this city". On 23 August 1918, Lenin in his telegram to Tashkent wrote: "Germans agree to attack Baku provided that we would kick the British out of Baku".
