The Night Attack of Târgovişte (Romanian: Atacul de noapte de la Târgovişte) was a skirmish fought between forces of Vlad III the Impaler of Wallachia and Mehmed II of the Ottoman Empire on Thursday, June 17, 1462. The conflict initially started with Vlad’s refusal to pay the jizya (tax on non-Muslims) to the Sultan and intensified when Vlad Ţepeş invaded Bulgaria and impaled over 23,000 Turks and Bulgarians. Mehmed then raised a great army with the objective to conquer Wallachia and annex it to his empire. The two leaders fought a series of skirmishes, the most notable one being the Night Attack where Vlad Ţepeş attacked the Turkish camp in the night in an attempt to kill Mehmed. The assassination attempt failed and Mehmed marched to the Wallachian capital of Târgovişte, where he discovered another 20,000 impaled Turks and Bulgarians. Demoralised, the Sultan and his troops retreated.
