I think they expected to be set free, or at least really really hoped. It was a matter of faith. Moses had spoken with the Pharaoh a number of times before the plagues even began, and the Hebrews were aware of this. I'm certain they were all packed-up and ready to go well ahead of time, as per their faith in the power of their God to back Moses up. As far as physically getting the people out of the country... I'm rusty and I don't know. But I'm quite certain they were already organized. For example, all the Hebrews knew the last plague was coming. This is why they smeared the blood of a lamb on all their door mantles; to signal to the angel of death that they were followers of the lord (thus, the first passover) Knowing that a plague of this gravity was coming, I'm certain they believed Pharaoh would finally cave, and were prepared to leave at the first opportunity.
With all that said, the truth of the matter is that the book may not be historically accurate.
Also, don't forget the nature of their culture was very different than ours in the US. The Hebrews were reliant on word of mouth to communicate all news. Their systems of communication were very efficient.
Exodus 4.29-31 states Moses going to the elders first to proclaim the Lord's plan of departure. Their response to the news was worshipful. One can justifiably conclude the elders went back to their families/clans and spread the good news.
With this in mind, one can also conclude the Hebrew nation observed the plagues happening around them. They were not affected, which probably solidified their anticipation of departure.
The Hebrews were nomadic in nature. Even though they had been in Egypt 430 years, their dwellings were (fairly) easily transportable. So the ease of relocation coupled with their anticipation for departure most likely equated to their efficiency.
Finally, perhaps Ex 12.51 is saying the departure began one day as opposed to being completed in one day. The original word translated as 'brought' in most versions is more closely translated 'to bring out' which leaves room for one to assume the process was not complete by sundown.
OpinionEven the mightiest nation in the world, the USA, was not able to that in spite of its manpower and logistics to the victims of Katrina.Modern historian now concluded that the Exodus never happen. The Exodus is just a Jewish folklore.
Twelve.
They had been calling themselves Israelites since the time of Jacob, and that did not change at this time. See also:More about Hebrews/Israelites/Jews
The Hebrews themselves were the builders of the Hebrew civilization. Today they are called Jews.

They were the ancestors of the Jews, who originated with Abraham in approximately 2000 BCE.
According to The Bible there were 12 Hebrew tribes.(Genesis 49:1-28) Jacob fathered 12 sons and each became the paternal head of a family. These families became the 12 tribes of Israel (the Hebrews).
approximately 2000 BCE to the present. Present day Hebrew are called Jews.
Settling enabled the Hebrews to establish themselves consistently in a location and also consistently separate themselves as a group. With a location and the lack of a need to interact with other groups, the Hebrews slowly became a more typical and homogeneous people and their religious activities followed suit.
The Jews are descendants of the Forefathers, Abraham Isaac and Jacob, who themselves are from the older Hebrews, progeny of Shem, son of Noah.
The Hebrews' military was an army composed of Hebrews.
Abraham, his son Isaac and his grandson Jacob were Hebrews. Jacob took or was given the name Israel. His descendants called themselves the Children of Israel, or Israelites. They were still Hebrews. The Judaites were one of the Israelite tribes. Later, the kingdom of Judah was the last surviving Israelite kingdom, and the survivors of that kingdom, all of them Israelites and Hebrews, came to be known as Jews.
