Dear Editor:

This letter is to inform you, that there is a problem with your product that you showed me five days ago. It provokes me a strangle allergy and I found it to be dangerous and misleading for all the people.

The advert, which is for a hair shampoo called “The powerful” it has a misleading objective in which consist in eliminate the dandruff of the hair.  However we decided to send your product in a lab and they discovered that “The powerful” was done using toxic substances prohibited in humans.  In consequence, you were lying about your magic item, you tried to copy the formulate from a different shampoo called “EGO” so it has in consequence many problems with the people who apply the product on their hair and problems with the government.

You have a demand for your product because all my family suffered the consequences from your dangerous item. The demand is going to be required if you don’t pay me all the expenses we needed to cure all my family, This is my HSBC account 28473874297492387 please send me the money. I recommend you to stop producing “The powerful” and fix all the problems.

I hope you fix and pay all the people that bought your item and be very careful.

The Unfavorable Mortar Boats

The Unfavorable Mortar Boats

The mortar boats were, as Foote indicated, a project begun by General John C. Fremont in the early days of the war. The mortars themselves came from Fort Pitt Foundry in Pittsburgh. These 13-inch Seacoast Mortars, Model 1861 - the Army's latest and heaviest seacoast mortars. The Army Ordnance Department designed the weapon to arm coastal fortifications. The 13-inch mortar fired a 227 pound shells fired to a maximum range of 4600 yards. Unlike standard guns, the mortars fired the shells in a high, arching trajectory to fall on top of the intended target. The army designed these seacoast mortars to drop shells upon an enemy bombardment fleet attacking coastal fortifications.

As you can see this mortar has to be operated by soldiers and is also hard to command it because the reloading is very dificult but it is not all, they have to shoot and change the position very fast if they do not want to be detected by the enemy.

This is a mortar from the first world of war..

Second world war artillery

First world war artillery.

The first mortar

The shortage of materials and personal in the trenche wars avoided the devolopment of artillery, because factories in that age were engaged on rifles and machine guns so the producers did not have enough time to produce mortar, however soldiers produced improvied mortars.

Mortar

"Mortar as the last resource" 

A mortar was invented by Mehmed II. In 1551 it was used against a vessel and it worked, so this arm becomes as a necessary item in the war. This weapon was hard to use in the middle of a battle and easiy soldiers who operate the mortar can be shooted, it was better to use it inside of a trenche so the operators could use the mortar much better.

During the fist world war this arm was use as a compact prototype, however in the second world war all contries improved their desings, being better the Soviet and American models. 

Now the mortar range is about 6.000 meters.
