Q: During the American Civil War, the Union was the first to field a submarine. The French-designed Alligator was the first U.S. Navy sub and the first to feature compressed air (for air supply) and an air filtration system. It was the first submarine to carry a diver lock, which allowed a diver to plant electrically detonated mines on enemy ships. Initially hand-powered by oars, it was converted after 6 months to a screw propeller powered by a hand crank. With a crew of 20, it was larger than Confederate submarines. Alligator was 47 feet (14 m) long and about 4 feet (1.2 m) in diameter. It was lost in a storm off Cape Hatteras on April 1, 1863, while uncrewed and under tow to its first combat deployment at Charleston.
Can we conclude that did they use submarines in the civil war?

A replacement for the king size Snickers bar was launched in the UK in 2004 and designed to conform to the September 2004 Food and Drink Federation (FDF) ''Manifesto for Food and Health''. Part of the FDF manifesto was seven pledges of action to encourage the food and drink industry to be more health conscious. Reducing portion size, clearer food labels, and reduction of the levels of fat, sugar, and salt were among the FDF pledges. Mars Incorporated pledged to phase out their king-size bars in 2005 and replace them with shareable bars. A Mars spokesman said: ''Our king-size bars that come in one portion will be changed so they are shareable or can be consumed on more than one occasion. The name king-size will be phased out.''
