Meanwhile, in Saint Petersburg, preparations were already underway for an amphibious attack on Vyborg. The tools needed for the siege were taken from the Peter and Paul Fortress. On 4 April, Cyril Naryshkin, the first Commandant of Saint Petersburg, received orders for twenty 18-pounder guns to be sent to Viborg from Narva (through Saint Petersburg), "by land or by sea, whichever path is more convenient," and 9,000 cannonballs along with them. However, Naryshkin could not gather the artillery fast enough, and only on 25 April did he send the cannon to Kotlin Island, where Captain Solovoy received them.
