battle of Cesis was a huge victory for the Estonians, but the Iron
Division (Freikorps) and Baltic Landeswehr (local German militia) under
von der Goltz fell back to a strong position outside Riga, using the
water features to good advantage. There were only two portions which
were not behind rivers, lakes or canals, one of which was alongside the
Daugava River (Duna, Dvina) near Salaspils, which is where this
scenario occurs. The Estonians launched a number of attacks on this
position and were generally beaten back.
With negotiations for an armistice due to start in Strazdumiuza
(Strasdenhof ) the Estonians made one last attempt to breach the
Freikorps line, a general attack being launched early on 2 July. This
was unsuccessful and a truce was signed the following day.
This scenario is an attack of an unscouted position (and the defence
doesn't know what he is facing either) in terrain that tends to obscure
the enemy until he is quite close, so requires players with some nerve.
(This sort of blind barging about was fairly typical of the war.)
