Here follows a longer description of the battles fought in the archipelago.
Already on March 20th two groups of German troops had arrived Houtskär. On 24-25th the Finnish Archipelago Free Corps (Skärgårdens frikår SFK) had moved there and made on 28th an attack against the Reds stationed at Korpo mansion. After losing almost 20 men the Reds retreated partly to Nagu and partly to the Russian barracks on Lohm island.
The main German group arrived Houtskär on April 2nd led by Captain Schweinberg. He decided to attack with two detachments, one against Nagu and the other against Lohm. In the morning the troops moved with horses over the ice.
The right flank of a group of Germans and the 1st Company of Free Corps attacked against the Lohm barracks, which held due to the advantageous location.
The left flank of three groups of Germans and the 2nd Company of Free Corps took the Mielis village on the north side of Nagu main island. The Reds lost almost 40 men, 12 prisoners, one machine gun and all supplies. In the attack against Thoras the Germans met an overwhelming enemy and could not move forward.
In the evening the Reds got reinforcements from Turku in the form of the Russian gun boat Bobr and ice breakers Murtaja and Snjek, which appeared in the rear between Houtskär and Nagu. Therefore Captain Schweinberg ordered the troops to retreat to Korpo mansion.
The red troops in Nagu embarked the ships to reinforce the troops in Lohm. It was prevented by the German cruiser Kolberg, which arrived with the help of the ice breaker Sampo. The crew of Murtaja left the ship and fled over ice to Turku.
On April 6th the Åland detachment was ordered to Finby to be shipped to Hanko, but the Archipelago Free Corps decided to continue to Turku. In the evening of April 13th, SFK arrived to Turku, which Red and Russian troops had already left and e.g. sunk 13 ships.
