In 1944, between November 14 and December 9, there were fierce battles between SD and SS units from the German 16th Army, under the command of Police General Friedrich Jekeln, and a separate battalion of the Kurelians, under the command of Lt Roberts Rubenis. The battles were waged in the Ugāle, Usma, Renda and Zlēki parishes. Rubenis’ men were well-armed and organised. There were more than 600 troops, and the soldiers saw themselves as a national force which stood apart from the two hostile occupant regimes. This was the longest and most extensive battle in the history of Latvian national resistance. As the military force of the Latvian Central Council, the unit enjoyed extensive public support and confirmed a high level of morality in fighting for the restoration of a democratic Latvia.

A memorial to Finnish soldiers in Klapkalnciems – five such soldiers from World War I are buried here. The memorial was first installed in 1929, but it was destroyed by the Soviet authorities. It was recreated in May 2004. The Lapmežciems Museum features photographs and more information about the Finnish soldiers.

This military object ensured radio communications. Now the facility is owned by the Latvian Defence Ministry, and it can only be viewed from the outside.
