Jerzy was invented in the mid 1930-ies in Czechoslovakia. In the Czech version of the fortifications were made of metal profile. Design proved to be quite massive. But in fact, they never visited because Hitler got the Czech territory virtually without firing a shot after the Munich agreement. In the USSR anti-tank barriers modernized major-General of technical troops Mikhail Lvovich Worricker.
Photos of the urchins on the streets of Moscow are presented in the pictures of the Museum mos.ru. The decision of Gorriceta was to reduce the size of the hedgehog. Although visually it looked very menacing for a multi-ton colossus to attack this obstacle to the tanks was impossible. Testing the so-called “stars of Gorriceta” showed that if the tanker try to push a hedgehog, he rolled under the car. The armored car started to slip and lost the ability to move. In some cases, the hedgehog just punched beams to the tank design. But even if this did not happen, it is offensive in any case would stay. Because the immobilized tanks are relatively easy to destroy. First, these barriers have been tested in the defense of Kiev in 1941.
In Moscow on the creation of “stars” let the high-profile Palace of the Soviets, who in those years was planned to be built in the city. On the streets of the capital and on the outskirts was established more than 37 thousand urchins. The Germans never managed to enter the city, so hedgehogs in the battle have not visited. Nevertheless, they have become symbols of the defense of Moscow.
in addition to hedgehogs, the defense of the capital symbolize the balloons, as well as multiple types of weapons fighters. All of this can be seen on the website of the Museum of defense of Moscow, digitized photographs and most important documents of the age of war.
