It is interesting how the author presented the Soviet actions as arbitrary, while the Third Reich’s actions come across as comprehensible and less irrational by comparison. Example:

Prior to, but especially following, the arrival of the German army in Estonia, indigenous forces organised in reaction to Soviet mobilisations or deportations, which had forced people, known as the Waldbrueder (forest brethren), to hide in the woods.

As the [Axis] approached, resistance groups formed, consisting of nationalists, former army personnel and former defence force members (Kaitseliit) and organised themselves together with the Waldbrueder into a self‐defence force, the Omakaitse. In conjunction with and under supervision of [Wehrmact] and police forces, the Omakaitse conducted the ‘cleansing’ of Estonia of communists and other ‘hostile’ elements.

Nonetheless, if you can overlook the author’s liberalism then this is certainly worth reading:

It can be deduced from the files who was considered an enemy of the ‘existing order’ and of Estonian national interests. These ‘phantom’ enemies included the following:

1. Members of the underclass, including farm hands, unskilled workers, and so on. This group was targeted because many held communist and socialist views, were open to Soviet propaganda and spoke in favour of the Soviet system. Participation in any activities connected with the Soviet authorities, even if innocuous, such as reading communist poems, wearing a red armband or kerchief, organising a ‘red corner’, were considered reprehensible. The underclass had the most to gain from the changes the Soviet occupiers initiated, such as free schooling, and were suddenly eligible to participate in the new, Soviet‐style institutions through administrative functions and voting committees. Particularly explosive was the issue of land reform. Persons who had been active in setting up trade unions for farm hands or the so‐called ‘new farmers’ (Neubauern) were specifically targeted after July 1941. The Soviet period was seen as an uprising of the lower classes against the wealthy. Farmhands had become ‘hochmuetig und frech’ (arrogant and uppish) and had to be put in their place again. Interestingly enough, one woman was sentenced for saying: ‘es werden soviele unschuldige Menschen erschossen, vorwiegend aus der aermeren Volksschicht’ (so many innocent people are being shot, in particular from the poorer ranks of society).

(Emphasis added. Evidence such as this does not mesh nicely with the antisocialist factoid that most, if not all Estonians abhorred the Soviets and hated every second of their presence.)
