 The Emperor's tutor, however, a certain Theodore, turned to Romanos Lekapenos; although the admiral carried a great share of the blame for the failure of the Bulgarian campaign, Romanos remained a powerful factor as his fleet was intact and ready at hand.The "parakoimomenos" Constantine tried to neutralize this threat by disbanding the fleet, but he was arrested by Lekapenos when he arrived to supervise the payment and discharge of the crews.With this stroke, Zoe lost all control of the situation, and at Theodore's urging, the young Emperor appointed the Patriarch Nicholas Mystikos as regent.
