The First World War brought promotion to captain and an Iron Cross 1st Class, but he was not one of the select few officers who were retained in the Weimar Republic’s new army, restricted to 100,000 men under the terms of the Treaty of Versailles.

He received his final promotion to major general (Generalleutnant) on New Year’s Day 1942, and was simultaneously awarded the War Merit Cross 1st Class with Swords.

The 302nd Infantry Division under Konrad Haase garrisoned Dieppe, 50 miles of coastline on either side of the town, and the area around the port; this was the unit that would defend against the raid.

[5] After his success in defeating Operation Jubilee during the Dieppe raid, Haase was congratulated in person by OB West, Field Marshal Gerd von Rundstedt and awarded a clasp to his Iron Cross 1st Class.

When 302nd Division was upgraded and moved to the Eastern front, Haase was removed from command and spent the rest of the war in staff positions in the Soviet Union, France and Italy.
