In 1984, Winston and Julia are at Victory Square and watch a convoy of trucks passing. What is their primary cargo?

In Part Two,
Chapter One,andsee a convoy of trucks pass through Victory Square. These trucks are carrying
human cargo: that is, a group of Eurasian prisoners. This prompts a
"din of shouting" and people to gather in crowds, eager to catch a glimpse of the
prisoners.

Remember that for much of the story, Oceania is at war with
Eurasia, hence the capture of these men. For the crowd, they are objects of hate but, for
Winston, they are people to be pitied:

"Their sad,
Mongolian faces gazed out of the side of the trucks utterly incurious."

These men are likely on their way to be executed as prisoners of
war. But later, in Part Two and during Hate Week, Oceania will switch sides, declaring peace
with Eurasia and war with Eastasia, and proving the Party's fickle
nature.
