Milk and dairy foods are an important part of our diet, providing many nutrients including proteins, minerals and vitamins essential for growth, bone and dental health. It is therefore important that if you think that you or your baby may be allergic to cowsâ milk, you speak to a GP or Health Visitor about it.
The first cannon in Europe were probably used in Iberia, during the Islamic wars against Spain, in the 13th century; their use was also first documented in the Middle East around this time. English cannon were first used during the Hundred Years' War, at the Battle of CrÃ©cy, in 1346. It was during this period, the Middle Ages, that cannon became standardized, and more effective in both the anti-infantry and siege roles.
By the 16th century, cannon were made in a great variety of lengths and bore diameters, but the general rule was that the longer the barrel, the longer the range. Some cannon made during this time had barrels exceeding 10 ft (3.0 m) in length, and could weigh up to 20,000 pounds (9,100 kg).estern cannon during the 19th century became larger, more destructive, more accurate, and could fire at longer range. One example is the American 3 in (76 mm) wrought-iron, muzzle-loading rifle, or Griffen gun, used during the American Civil War, which had an effective range of over 1.1 mi (1.8 km).
