Finnish WWII Battles by Name, With Dates (WarSampo)

ldfwarsa/search-battles

Searches the WarSampo Knowledge Graph for Finnish Second World War battles whose English name contains the text you give, case-insensitively: returns the battle IRI, its English label and its start and end dates (xsd:date), oldest first. Give a name fragment of 2 to 60 characters, for example summa or tali, and a result count of 1 to 100. A name that matches nothing returns an empty list.
