not surrender. The resistance, however, continued for another hour, when a German envoy arrived carrying a flag of truce and proposed a cease fire. It lasted until approximately 1:30 p.m. Raginis, realising that all of his men were wounded and his ammunition was almost depleted, ordered his men to surrender their arms to the Germans. He himself – seriously injured at the time – refused to surrender and committed suicide by detonating a grenade against his neck. Aftermath After the Polish resistance ended, the XIX Panzer Corps advanced towards Wysokie Mazowieckie and Zambrów, where it fought the Battle of Zambrów against the Polish 18th Infantry Division, finally encircling and destroying the Polish division during the Battle of Andrzejewo. Later it advanced further southwards and took part in the Battle of Brześć. Although all the bunkers were destroyed and the Polish resistance was finally broken, the fortified area of Wizna managed to halt the German advance for three days. The heroic struggle against overwhelming odds is one of the symbols of the Polish Defensive War of 1939 and is a part of Polish popular culture. Casualties Exact Polish losses are unknown, mostly because very little is known of the soldiers that were taken as prisoners of war by the Germans. Out of 720 Polish soldiers only approximately 70 survived. Some successfully withdrew and reached the Polish lines, others were taken prisoner. Some of the prisoners were subsequently killed by the Germans, others were beaten and abused but survived and were eventually taken to POW camps. German losses are not known either. An official release by the Wehrmacht mentioned "several dozen dead". The Wehrmacht lost at least 10 tanks and several other AFVs in the struggle. The history of the 10th Tank Division for September 8 mentions 9 killed and 26 wounded in action for the ALA. The I./IR 86, which was the main unit of the capture of the bunkers reported on September 9 at 17:00 the loss of 40 men. There are some losses of the Tank Regiment 8 reported as well. The following fighting at Wysokie-Mazowieckie and Andrzejewo make it difficult to differentiate the losses. In popular culture The Battle of Wizna is the theme of the song "40:1", on the album The Art of War by the Swedish metal band Sabaton. The title comes from the disparate ratio of forces and the lyrics compare the Polish forces with
