Often, the beholder is the judge of the answer; or the latter depends on the moment of reflection on past events. Dutch 17th century history mentions four sea wars with the English. English history
The 100 year war between chemistry and bacteria, in 100 episodes

As soon as World War I had ended, research on infections soared. There was pressure to come up with results, much pressure. Bacterial infections had been responsible for most casualties in the muddy trenches. In the previous decades, researchers had isolated and characterized many of those bacteria. Chemistry and chemical industry developed several lines of
