Winston is in the Chestnut Tree Cafe, listening to the telescreen. Hearing the trumpet the people knew that Oceania had a victory.
Everyone l went wild, shouting and cheering while an excited voice was gabbling from the telescreen. Winston had to strain to hear the words of the announcer. It was just as he had foreseen. There had been a vast seaborne armada which had secretly assembled and dealt a sudden blow in the enemy’s rear.
Fragments of triumphant phrases uttered by the announcer pushed themselves through the cheering:
‘Vast strategic manoeuvre — perfect co-ordination — utter rout — half a million prisoners — complete demoralization — control of the whole of Africa — bring the war within measurable distance of its end victory — greatest victory in human history — victory, victory, victory!’

There was a time Winston knew this was pure propaganda. He never listened to the reports. Since his torture he is taking these reports as real. The change in his thought processes is obvious to the reader.
