Early years Guido came from the Pomeranian noble family Usedom and was the son of Lieutenant Kuno von Usedom (1804–1855). He joined the
Imperial German Navy on May 31, 1871. After his training and his first tours of duty on board, he was given his first command. For a time he served as adjutant to Prince
Henry of Prussia. In October 1895, Usedom, with the rank of
Korvettenkapitän (Lieutenant Commander), was in command of the
aviso (dispatch vessel)
SMS Pfeil until the end of the year, and from March 1896 he was in command of the aviso
SMS Jagd for six months. From September 1896 to July 1898 he was in command of the coastal defence ship
SMS Hagen and was made a Senior Korvettenkapitän during this time. He then took command of the large cruiser , which had just been put into service, on which he was promoted to the new rank of
Fregattenkapitän (Commander). He was eventually promoted to the rank of
Kapitän zur See (Captain) on September 18, 1899.
The Boxer Rebellion Usedom was deployed with Hertha in the
Mediterranean and
East Asia. At the beginning of the
Boxer Rebellion, the commander of the
East Asia Squadron, Vice Admiral
Felix von Bendemann, ordered a landing corps to be formed from the crews of all German cruisers to help protect the European embassies in
Beijing. Usedom became the leader of the entire German expeditionary force of around 500 men, which was subordinate to the British commander of the foreign armed forces involved, Vice Admiral
Edward Seymour. Usedom simultaneously served as its chief of staff. On June 10, 1900, the entire expeditionary force left
Tanggu by rail for Beijing. The advance was stopped by Chinese troops and insurgents, so that the expeditionary force had to withdraw by land. The commander of the British landing corps, Captain
John Jellicoe, who later became the commander of the Grand Fleet in the
Battle of Jutland, was wounded. In this distressed situation, Seymour requested the use of the German troops under Usedom and is said to have spoken the historical phrase "The Germans to the Front". Due to his experience with the landing corps, Usedom was released from the leadership of Hertha in September 1900 and assigned to the staff of the commander-in-chief of the allied troops in
China, which enforced the end of the uprising. Parallel to this task, he had already been formally appointed as wing adjutant to the emperor on July 21, 1900. On April 5, 1902, Usedom was awarded the
Pour le Mérite for his achievements in China.
Before the First World War In August 1902, Usedom took command of the imperial yacht
SMY Hohenzollern, which he held until October 1904. He then became Inspector of the I. Marine Inspection and in this capacity was promoted to Rear Admiral on March 14, 1905. At the same time he was from September 1905 the deputy director, and from January 1906 director, of the
Imperial Shipyard Kiel. On August 21, 1908 he was promoted to Vice Admiral and with his retirement at the end of 1910 was
given the character of Admiral.

World War I, Usedom was reactivated and sent to
Constantinople as head of the Special Command Turkey. Because of increasing signs for a
Triple Entente operation against the
Dardanelles, and thus the risk of a siege and eventually fall of the capital of the
Ottoman Empire, increased Usedom was
seconded to the
Ottoman Navy. Given the rank of
Mushir, he was appointed Commander-in-Chief of the Straits. Having extremely limited resources, Usedom expanded his coastal positions while having inadequate garrisons in the forts further inland. By mid-February 1915, Usedom managed to man the heavy artillery in the most important forts along the straits and to lay extensive minefields in the straits. The French battleship
Bouvet and the British battleships
Irresistible and
Ocean were sunk by these mines in the course of the Dardanelles campaign. The further course of the beginning
Battle of Gallipoli was determined less by Usedom than by the leadership of the Turkish land forces in form of the German general
Otto Liman von Sanders. Usedom as awarded the Oak Leaves to his Pour le Mérite in August 1915, and after the campaign had ended remained in Turkey and in Ottoman service. In January 1916 he also received the substantial promotion to Admiral. He retired on November 26, 1918. ==References==
