Harald Riipalu (born as Harald Reibach) (13 February 1912 – 4 April 1961) was an Estonian commander in the German Wehrmacht and the Waffen-SS during World War II. He was a recipient of the Knight's Cross of the Iron Cross of Nazi Germany.
After the Soviet occupation of Estonia in 1940, Riipalu was forcibly mobilized into the Soviet Army 22nd Territorial Corps, serving until 1941, at which time he defected to the German side.
From 1942 to 1943 Riipalu was a platoon leader and company commander of the 36th Estonian Police Battalion, and became commander of the battalion in November 1942.[1]
From 1943 to 1945, he served in the 3rd SS-Brigade and the 20th Waffen Grenadier Division of the SS. He was the Commander of the 45th SS-Grenadier Regiment from April 1944. On 23 August 1944 he was decorated with the Knight's Cross of the Iron Cross for his actions in the Battle of Tannenberg Line and in the Battle of Auvere where Riipalu and his regiment drove back the assault of the Soviet Army, which prevented the encirclement of Army Detachment Narwa. The award was presented to him by Felix Steiner, the commander of III SS Panzer Corps.
After the end of the war, Riipalu evaded Soviet captivity by fleeing to Denmark. He died in Great Britain in 1961.
