On the night of 25 November 1741 (O.S.), Elizabeth seized power with the help of the Preobrazhensky Regiment. Arriving at the regimental headquarters wearing a warrior's metal breastplate over her dress and grasping a silver cross, she challenged them: "Whom do you want to serve: me, your natural sovereign, or those who have stolen my inheritance?" Won over, the regiment marched to the Winter Palace and arrested the infant Emperor, his parents, and their own lieutenant-colonel, Count Burkhard Christoph von Munnich. It was a daring coup and, amazingly, succeeded without bloodshed. Elizabeth had vowed that if she became Empress, she would not sign a single death sentence, an extraordinary promise at the time but one that she kept throughout her life.
