The campaign map identifies Gotland, the Åland Islands, and Sveaborg as positions that required permanent garrisons and reliable communications. Sweden needed a continuous link to Sveaborg, maintained by couriers across the ice or ships in open water, so the government always knew the state of its critical base. Instead, the Finnish commander arrived only after the war had begun and inherited incomplete command arrangements. Gustav IV Adolf had delayed mobilization and reinforcements despite Russian threats dating from September 1807. Even modest winter deployments of engineers, timber, supplies, and trained troops could have repaired gun carriages and fortifications before the invasion. Such visible preparation would also have shown Finland that Sweden intended to defend it rather than leave local communities to calculate the cost of resistance alone.

Baltic defence required communications before the invasion
Ungarrisoned islands, weak links to Sveaborg, and a commander dispatched after hostilities began left Sweden without the information and readiness its maritime strategy required.
