Deuteronomy 2

what I remember:
Mosese continues his life-end speech to Israel - with the history continued.  The traveled through the desert for 38 years.  The passed through the land of Esau, and God warned them not to fight, because that was the land he'd given to Esau, not to them.  The same for the land that God had given to the descendants of Lot.  But the land of the Amorites was theirs.  So they were told to actually go and fight the Amorites - to facilitate this, he had Sihon, the king of the Amorites attack them.  They completely cleaned up - killed all the people, and saved only the cattle and loot for them.  They conquered every town.

key verse:
The Lord your God has blessed everything you have done.  He has protected you while you travelled through this large desert.  The lord your God has been with you for these 40 years.  You have had everything you needed.

about God:
He keeps His word.  Again.
He provided everything they needed in the 40 years - just like he promised.
He didn't allow them to enter the promised land until everyone of fighting age from the generation that refused to go in and fight had died. God promised to make the Amorites afraid of them, and promised that they'll beat him.  They completely wipe him out.

"But Sihon king of Heshbon would not let us pass.  The Lord your God had made him stubborn.  The Lord wanted you to defeat Sihon.  And now this has happened."  "The Lord said to me, "See I have begun to give Sihon and his country to you.  begin taking the land as your own."

This is the first of the pair that's so frequently referred to in other parts of the Bible - Sihon, king of the Amorites and Og, king of Bashan.  This victory was famous - and for a reason.  God delivered big time, and the people did as they were told and completely destroyed the nation.
