Interesting facts "Military affairs" Interesting facts about barbed wire
In May 1872, Illinois farmer Henry Rose patented a wire fence with spiked planks nailed down to guard livestock. American J. Glidden improved the design of barbed wire, he made thorns with a coffee grinder and wrapped them around the wire. To prevent the spikes from moving, Glidden wrapped them with another wire.
Barbed wire became so popular in the United States that 270 tons of barbed wire were produced in 1875, and by 1900 production had increased to 150, 000 tons.
Barbed wire was first used against humans in the United States. In 1892, during a miners' strike in Idaho, mine owners locked the strikers in their own town with barbed wire. Many of the 1, 200 miners died in this world's first private concentration camp.
The military quickly adapted the barbed wire to suit their needs and made barriers out of it to slow down the movement of the infantry. One of them is the "Bruno spiral", which is difficult to overcome even with the wire cutters, since you need to bite at least 6-7 points of the wire attachment.
Hand grenades, forgotten since the 18th century, owe their rebirth to barbed wire. They were remembered in the process of searching for a means of overcoming wire obstacles. Most WWI hand grenades have three to six laces with hooks at the ends. The grenade threw itself on the fence, hooked and hung. The explosion damaged several strands of wire.
The weight of a coil (340-400 meters) of wire, depending on the design of the spikes, is only 35-50 kilograms. In the Soviet Union, the barbed tape received the code name "Egoza" and consists of a metal tape with blades, which is crimped around the wire. They began to twist this tape into a spiral. The coils of the spiral are connected in 3-11 places with the help of wire, tape or metal staple. When this spiral is stretched, an insurmountable cylindrical barbed fence is formed.
In the United States of America, as the historical homeland of barbed wire, it is very popular to collect its samples, especially from the first decades of production.
