In the early morning of April 9th 1940 the Danish army is alerted. The Germans have crossed the border; Denmark is at war against Europe’s strongest army. In Southern Jutland Danish bicycle- and motorcycle companies are ordered out, to against all odds, hold back the forces until the Danish reinforcements can be mobilized. In the fatal hours, we follow second lieutenant Sand (Pilou Asbæk) and his bicycle company – they will as the first Danish soldiers meet the enemy in combat on April 9th 1940.—Nordisk Film Production A/S
While bicycle troops might seem risible and impractical to modern eyes, such units were in fact quite common in many countries at the time, including Germany, fielding whole bicycle battalions. Early in World War Two, Japan conquered much of China and South East Asia employing some 50,000 bicycle infantry, such troops taking e.g. Singapore from Great Britain. Bicycle units were also employed by the British during the invasion of Normandy in 1944. Bicycle infantry was seen as cost effective mobility in place of e.g. horses, that needed extra feed and could panic under fire.
