A
One warm May day, two eighteen – year – old students from San Francisco State College decided to cool off with a swim at Bakers’ Beach. The two students were named Robert Kogler and Shirley O’Neill. They headed out to sea for a distance of 50 metres. Robert was in front.
“Suddenly, I heard him scream,” Shirley recalls. “I looked round and saw this great grey thing going up in the air. The water seemed to be alive.”
Robert sereamed again. “It’s a shark! Get out of here!”
An eye – witness, Army Sergeant Leo P. Day was on guard at the nearby army post. He saw exactly what happened next. “I could see this boy struggling with the shark in the water,” he said. “The sea was red with blood. He was shouting and signalling someone to go back, go back. Then I saw the girl. She was swimming towards him. She completely ignored his warning.”
Shirley reached Robert, and tried to take his hand.
“When I pulled, all I could see was his arm, handing by a thread,” she said.
So she put her arm about Robert’s back, and started to swim towards the shore. She kept praying “Don't’ let it attack again!” That journey to the shore seemed to last for hours. At last, as they neared the shore, a fisherman threw them a line, and pulled them both the rest of the way.
The young man had lost a lot of blood, and died two and a half hours later, From the teeth marks, experts identified the attacker as a Great White Shark.
For what Sergeant Day called “the greatest exhibition of bravery I have ever seen,” the President of the US gave Shirley a medal for bravery.
