At the very beginning of the Continuation War the 7th Coastal Brigade took up positions in the Åland Islands. The only significant event at the beginning of the Continuation War was the Battle of Bengtskär (26.-27.7.1941), where a force from the Soviet Union naval base in Hanko attempted to invade the island of Bengtskär. The coastal batteries of Örö supported the Finnish defenders, and a counter-attack force from the men from Örö and Hiittinen repelled the invaders. Otherwise the action in the area was limited to Soviet air activity. The 5th Coastal Brigade was transferred to East Karelia and reformed as the Lake Onega Coastal Brigade. 7th Coastal Brigade was thus the only unit remaining in the Archipelago Sea area, and it became the Archipelago Sea Coastal Brigade ("Saaristomeren Rannikkoprikaati")) on 1.3.1942. Hiittinen Sector, formerly part of the Hanko Group, became also part of the brigade. The brigade was reorganized on 29.4 as two coastal artillery regiments, the 7th on Archipelage Sea and the 17th on Åland Islands, plus Bothnian Sea coastal guard and units directly subordinated to brigade headquarters. With the Soviet Baltic Fleet trapped at the eastern end of the Gulf of Finland the threat for the brigade was low and the regiment headquarters were not established and only the most important forts were manned.
