Timofey Yashchik was born on April 20, 1878, in the village of Novominskaya in Kuban. In 1900, he was drafted into the Yeisk regiment, stationed in Tiflis. Due to his impressive appearance, he was soon appointed to the Escort of the Commander of the Caucasian Military District, General-Adjutant Prince E. S. Golitsyn. In 1904, Yashchik arrived in St. Petersburg with Golitsyn and was enrolled in the Second Kuban Hundred of the Imperial Own Escort. Here, the Cossacks were trained in guard duty, equestrian skills, shooting, and navigation. Three years later, he resigned and lived in his native village until 1912, when he was called back to the Own Escort. His service ended in 1914, during which time Nicholas II selected him for the position of chamber Cossack. Yashchik considered his duties formal and uncomplicated, the main one being his constant presence with the emperor. He served under Nicholas II for nine months. In early 1916, Yashchik became the second personal bodyguard of the Dowager Empress Maria Feodorovna. After 1917, he continued to guard her in Crimea. In 1918, Yashchik helped evacuate Nicholas II's younger sister, Grand Duchess Olga Alexandrovna, to her native village, where she gave birth to her second son, Guriy. Later, he organized the family's departure abroad. After Maria Feodorovna left Russia, Yashchik accompanied her in England and Denmark, guarding her until her death in 1928. After that, Yashchik remained in Denmark, married a Danish woman, and opened a shop with a small inheritance left by the empress. Timofey Yashchik passed away in 1946 and was buried alongside his wife in a Russian cemetery.
