In one of the coldest Decembers that Turkey had seen for years, Bahá'u'lláh and, His family -- including His two faithful brothers Mirza Musa, entitled Aqay-i-Kalim, and Mirza Muhammad-Quli, together with Mirza Yahya -- set out on their journey to the city of Adrianople. The officer commissioned to take charge of the journey was 'Ali Big Yuz-Bashi. According to a statement by Mirza Aqa Jan, it appears that Bahá'u'lláh was accompanied by 12 of His companions. Among them was the notorious Siyyid Muhammad-i-Isfahani, whose evil spirit was increasingly casting its shadow upon the exiles. Through his satanic influence he brought much pain and anguish to their hearts and created severe tests and trials for them. (Adib Taherzadeh, The Child of the Covenant, p. 77)
Here is how Shoghi Effendi describes this very sad and inhumane event:
Pursuant to the peremptory orders issued for the immediate departure of the already twice banished exiles, Bahá'u'lláh, His family, and His companions, some riding in wagons, others mounted on pack animals, with their belongings piled in carts drawn by oxen, set out, accompanied by Turkish officers, on a cold December morning, amidst the weeping of the friends they were leaving behind, on their twelve-day journey, across a bleak and windswept country, to a city characterized by Bahá'u'lláh as "the place which none entereth except such as have rebelled against the authority of the sovereign." "They expelled Us," is His own testimony in the Suriy-i-Mulúk, "from thy city (Constantinople) with an abasement with which no abasement on earth can compare." "Neither My family, nor those who accompanied Me," He further states, "had the necessary raiment to protect them from the cold in that freezing weather." And again: "The eyes of Our enemies wept over Us, and beyond them those of every discerning person." "A banishment," laments Nabil, "endured with such meekness that the pen sheddeth tears when recounting it, and the page is ashamed to bear its description." "A cold of such intensity," that same chronicler records, "prevailed that year, that nonagenarians could not recall its like. In some regions, in both Turkey and Persia, animals succumbed to its severity and perished in the snows. The upper reaches of the Euphrates, in Ma'dan-Nuqrih, were covered with ice for several days -- an unprecedented phenomenon -- while in Diyar-Bakr the river froze over for no less than forty days." "To obtain water from the springs," one of the exiles of Adrianople recounts, "a great fire had to be lighted in their immediate neighborhood, and kept burning for a couple of hours before they thawed out."
Traveling through rain and storm, at times even making night marches, the weary travelers, after brief halts at Kuchik-Chakmachih, Buyuk-Chakmachih, Salvari, Birkas, and Baba-Iski, arrived at their destination, on the first of Rajab 1280 A.H. (December 12, 1863), and were lodged in the Khan-i-'Arab, a two-story caravanserai, near the house of Izzat-Aqa. Three days later, Bahá'u'lláh and His family were consigned to a house suitable only for summer habitation, in the Muradiyyih quarter, near the Takyiy-i-Mawlavi, and were moved 162 again, after a week, to another house, in the vicinity of a mosque in that same neighborhood. About six months later they transferred to more commodious quarters, known as the house of Amru'llah (House of God's command) situated on the northern side of the mosque of Sultan Salim. (Shoghi Effendi, God Passes By, p. 161)
Bahá'u'lláh was now virtually a prisoner of the Ottoman government.
