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.
Halloran's visuals of all the U.S. military deaths in World War II are shown below. Each figure represents 1,000 deaths. On D-Day, approximately 2,500 American troops died, more than in the entirety of the U.S. war in Afghanistan. Our ancestors, it seems, were made of stern stuff. During the later Battle of Okinawa, America's bloodiest single clash in the Pacific, around 12,500 Americans lost their lives.
