Why was barbed wire used in ww1

However, while barbed-wire fences were made of the same wire, they had barbs that deterred cattle from crossing after one or two attempts. A series of harsh winters killed hundreds of cows and damaged the cattle industry pretty substantially around that time and work as a cowboy was not profitable. The cowboys hated the wire: cattle would get nasty wounds and infections. When the blizzards came, the cattle would try to head south.

And while barbed wire could enforce legal boundaries, many fences were illegal — attempts to commandeer common land for private purposes. The cowboy played only the briefest of roles in American history, before the farmers and settlers came in. More cowboys were killed by falls and lightning than by bullets. Barbed wire, the most commonly used cattle fence, has a built-in physical barrier. Five strands of barbed wire is recommended, but that can vary.

A strand of barbed wire or electric wire along the top of a woven wire fence prevents cattle from leaning over the fence, Edwards says. With a breaking strength of 1, lbs. Class 1 Galvanized — This is the most basic type of coating, used on barbed wire and field fences. Class 3 Galvanized — This is a stronger, longer-lasting zinc coating. Whereas Class 1 wire coating uses 0. Most electric fences use 14 or 17 gauge wire depending on how long the fence is and what animal is being contained or repelled.

Keep in mind that the lower the gauge of wire, the thicker the wire will be. An acre is a unit of area, it is square feet, but it can be any shape, a square, a circle, a long thin rectangle, a triangle, pie shaped or any other shape. If it is feet wide then it is feet long and the perimeter is feet. The distance around a 5 acre property depends on the shape, not just the area. If this property is a square then each side is of length If there are , square miles, there are , miles in one direction say east — west and , miles in the north-south direction.

Thus , To scare the bear away, make loud noises by yelling, banging pots and pans or using an airhorn. Make yourself look as big as possible by waving your arms.

If you are with someone else, stand close together with your arms raised above your head. Why bears lose their fear of humans Bears are normally wary of people, but if a bear finds food without getting frightened away, he may come back for more.

Each time this happens, he can become less fearful—and this habituation can lead to problems. This kind of attack is very rare, but can be serious because it often means the bear is looking for food and sees you as prey. Bear pepper spray can be an important thing to carry when exploring the back country. Polar bears, particularly young and undernourished ones will hunt people for food.

Truly man-eating bear attacks are uncommon, but are known to occur when the animals are diseased or natural prey is scarce, often leading them to attack and eat anything they are able to kill.

A bear will eat you alive in certain conditions. He wrote that, when attacking humans, black bears will rear up on their hind legs and knock victims over with their paws. They then make one or two bites on an arm or leg and finish with a snap to the head, this being the most dangerous part of the attack. Your best chance of survival against a black bear attack comes from fighting back.

Bears are NOT ferocious. They are NOT mean or malicious. Bears are normally shy, retiring animals that have very little desire to interact with humans.

Unless they are forced to be around humans to be near a food source, they usually choose to avoid us. The venom bulb acts like a pump to deliver venom through the venom duct into the harpoon, injecting it into the prey. The rostrum acts like a mouth, engulfing the prey in one big chomp. Some hours later, the snail burps out any indigestible fish parts such as scales and fish bones, along with one used harpoon.

Of all the species in the world, the largest—and most dangerous—is the saltwater crocodile. These ferocious killers can grow up to 23 feet in length, weigh more than a ton, and are known to kill hundreds each year, with crocodiles as a whole responsible for more human fatalities annually than sharks.

Here is a list of 13 unlucky animals that are still killed in wildlife killing contests across the country. Herbivores that are too big for a tiger to handle: Elephants, rhinos although there are exceptions to that one and hippos. Predators that can take on a big tiger in a head-on fight: Big, male brown bears, polar bears and large c.

Dally was so hurt over the loss of a brother-like-friend, he threatened the police with an bullet-less gun and the police shot and killed him.

No one risked their own life to go back and help out the injured soldier. The way Behm died was harsh and painful as the author described him being shot. After being forced to shoot the horse with the broken leg, the image of falling haunts Robert where Findley. Because of this literally cutting-edge bullet, many soldiers were in need of surgery, and since the surgeons were worried that the patients would catch disease from just letting the wound fester and also the blood loss, they decided to operate on many.

The surgeons and doctors would use unsanitary and reused bandages which is why Bromine became an important part of operations, cleaning the instruments and such. The whole of the United States and the future of the world learned from the diseases and injuries from the Civil War. A t4 ;30 bombs were hitting Fort Sumter and they were shot by the Confederates and after a thirty-four hours of fighting.

The small Union force inside Fort Sumter surrendered to the confederate army. The assault on Fort Sumter began the Civil War the North and South were split up and killed many thousands of soldiers and civilians. The Union victory ended slavery in but it cost in human life was immense.

The North has been known for having a larger amount of soldiers then the south Confederates. So far this has been the most bloodiest most terrifying battle of all because yesterday was the most Americans that have died in two battles combined. We will always and forever remember this day as the worst day in the history. Although almost a year part these two battles are both equally bad and very devastating to people all around the world and family and friends. Hundreds of woman children and old men died in a bloody massacre spoken of by Black Elk and President Harrison in the Wounded Knee Massacre document.

After World War I, countries were economically poor. World War II was a long and tiresome war that lasted for six years. Along with the war, a horrific event also took place called the Holocaust. In all, the war was horrible, but to understand why the war happened, one must start from the beginning.

Well this particular war was fought in trenches. Also known as trench warfare.
