The first construction works were started in April 1939. The spot was chosen carefully: most of the concrete bunkers were built on hills overlooking a swampy Narew River valley. They could be reached either through direct assault through the swamps or by attack along the causeway leading from the bridge in Wizna. Until September 1, 1939, 12 bunkers were built altogether. Six of them were heavy concrete bunkers with reinforced steel cupolas (8 tons of weight) while the other six were machine gun pillboxes. Additional four heavy bunkers were under construction at the moment the World War II started. In addition, the area was reinforced with trenches, anti-tank and anti-personnel obstacles, barbed wire lines and landmines. There were also plans of breaking the dams on the Biebrza and Narew rivers to flood the area, but the Summer of 1939 was one of the most dry seasons in Polish history and the level of water was too low.Is there a movie here? That isn't even the question. The question is why hasn't there been one made.
Although not all bunkers were ready by the beginning of the war, the Polish lines of defences were well-prepared. The walls of an average bunker, 1.5 metres thick and reinforced with 20-centimetre-thick steel plates, could withstand a direct hit from even the heaviest guns available to the Wehrmacht at the time. The bunkers were situated on hills which gave good visibility of all the advancing forces.
Any good movie needs a villain. The best movies have a villain who is a bit nuanced - or even better - there is some ambguity as to if he is evil at all. Notice any names?
On September 8 general Heinz Guderian, commander of the XIX Panzer Corps, was ordered to advance through Wizna towards Brzesz. By early morning of September 9 his units reached the Wizna area and were joined with 10th Panzer Division and "Lötzen" Brigade already present in the area. His forces numbered some 1 200 officers and 41 000 soldiers and NCOs, equipped with over 350 tanks, 108 howitzers, 58 pieces of artillery, 195 anti-tank guns, 108 mortars, 188 grenade launchers, 288 heavy machine guns and 689 machine guns. Altogether, his forces were some 40 times stronger than the Polish defenders.Who faced the great Guderian?
