In 983, the Danes reconquered the southern Schleswig area from the Germans. Some sites claim that the Danes conquered Holstein as well during this invasion and even sacked Hamburg in cooperation with the Slavs. Is is this true ? In particular, is there any evidence to support the sack of Holstein and Hamburg?
- For how long did the Danes hold it?
- Why weren't the Germans able to counter the Danish advance? apparently Otto 2 had taken Danevirke in 974, so it seems odd that in 10 years time the tide had turned totally against the Germans? was it simply a matter of good leadership?
- Were the battle/battles that took place during the reconquest of Hedeby 983 a lot of skirmishes or a big battle which crushed the German influence in the Schleswig area?
