Peter's plan for the second siege of Viborg involved a combination of land and sea forces, and the fort was to be taken by a prolonged siege. By February 1710, a specialized siege corps had been assembled on Kotlin Island. This time, the Russian attack came in two stages. On 2 March 1710, General Apraksin received orders to attack Viborg, and he planned to move out by 15 March. However, on 16 March, he was still on Kotlin Island, from where he wrote to Robert Bruce that he was departing on "the day of tomorrow". In fact, he only set out on 21 March, arriving with the cavalry on that same day at Vyborg; the infantry and cannon arrived the next day.
