Bacteria as plant pathogens can cause severe economically damaging diseases, ranging from spots, mosaic patterns or pustules on leaves (Figure 5) and fruits, or smelly tuber rots to plant death.
Size of force or number of deaths does not necessarily equate to worst - the question is not what was the largest defeat nor was it what was the defeat with the most casualties. As such, I would suggest that the worst defeat in US military history was the Battle of Little Big Horn, or Custer's Last Stand - a hastily decided attack by Custer left his troops ripe for the picking by the Soux and Apache warriors.
The battle was the last major German offensive on the Western Front during World War II. It is the largest battle the United States Army has fought to date. In its entirety, the Battle of the Bulge was the worst â in terms of losses â for the American Forces during World War II, with more than 80,000 American casualties.
