What happened 4 times at the threshold in the fall of troy?

In the fall of Troy, four significant events occurred at the threshold of the city: the Greeks, using the ruse of the Trojan Horse, managed to infiltrate the city; the Trojan defenders were initially deceived by the apparent gift; the Greeks emerged from the Horse at night, launching a surprise attack; and finally, the city was sacked, leading to its destruction and the end of the Trojan War. These events marked a dramatic turning point, culminating in the fall of one of history's most legendary cities.
