 As argued by Iorga, this account cannot refer to Cercel, but rather to his Moldavian rival, Ștefan Bogdan.By September 1602, Marcu was known to be camped with the Imperial Army at Corona, where Radu Șerban was preparing the reconquest of Wallachia.Marcu assisted in this effort, commanding a guard unit of 3,000 Székelys and 1,000 Transylvanian pikemen.
