Breadcrumb: All at once now

In Josh. 11, the northern kings of Canaan see that Joshua has completely destroyed their southern neighbours. So they band together, a huge host of armies, "even as the sand that is upon the sea shore in multitude," complete with horses and chariots. (Josh. 11:4) It should therefore come as no surprise that Joshua kills them all in a surprise attack. In fact, it seemed that the only useful thing accomplished by the banding was that it gave Joshua a single locale to attack instead of dozens of separate cities.
