The timeline of the attack;

According to the IDF’s investigation, the Hamas assault on Kfar Aza began shortly before 7 a.m. on October 7, but would only end in the afternoon hours of October 10 when the final terrorist remaining in the kibbutz was killed.

Only at 7:34 a.m. was a first text message sent to residents warning them of a terrorist infiltration.
The person normally responsible for the emergency messages, Dorit Wertheim, was killed at 7:28 a.m.

By 8 a.m., some 150 Hamas terrorists were inside the kibbutz.
The Golani troops, in a Namer armored personnel carrier (APC) breached one of the gates of the community and reached the southern neighborhood.

They responded to WhatsApp messages from resident Erez Yitzken, who was wounded after Hamas terrorists set off a bomb outside his bomb shelter and opened fire on him.

Israeli Air Force IAF drones and helicopters at the same time were carrying out several airstrikes in the area, mostly along the kibbutz’s security perimeter.

As night fell, some 1,000 Israeli troops were inside Kfar Aza. Still, around 50 terrorists remained, barricading themselves in homes.
It remains unclear why they remained in the kibbutz, instead of fleeing.

Only by 11 p.m. did the IDF begin an organized evacuation of residents from Kfar Aza, as it worked to get an accurate picture of the civilian situation there.
By Monday morning, October 9, there were 10-20 terrorists still in the kibbutz.

The bodies of 101 terrorists were located in the kibbutz, and another 50 were found outside.
Those killed outside Kfar Aza were mostly targeted from the air by the IAF drones and helicopters.
