Samwise finds Frodo in the Tower.
Minas Tirith is besieged.
The Rohirrim led by the Wild Men come to the Grey Wood.
I think this is the first mention of Sam, which makes sense because this moment was huge for him. When Frodo was stuck by Shelob, Sam thought he was dead. He had two options, to turn back or finish the quest. Sam choose the hardest task but in the end it was the right one.
While all this is going on Minas Tirith is getting overrun and everyone is trying to get there as soon as they can.
March is certainly roaring in like a lion.
Thank you for your time and remember, not all those who wander are lost.
