I want to know the answer to the following question:
Who was in control of the Danubian Principalities?
All the background I'm provided with is that "Shortly after he learned of the failure of Menshikov's diplomacy toward the end of June 1853, the Tsar sent armies under the commands of Field Marshal Ivan Paskevich and General Mikhail Gorchakov across the Pruth River into the Ottoman-controlled Danubian Principalities of Moldavia and Wallachia.". Is that enough to answer the question?
Answer: yes
