During a 10-month period the lions killed at least 28 people.
After the new attacks, hundreds of workers fled from Tsavo, halting construction on the bridge.
Patterson set traps and tried several times to ambush the lions at night from a tree.
The shot struck the lion in its back leg, but it escaped.
Later, it returned at night and began stalking Patterson as he tried to hunt it.
A shot through the heart eventually killed the lion.
The second lion was killed twenty days later.
Patterson had to fire at least nine times before it was dead.
He claimed it died gnawing on a fallen tree branch, still trying to reach him.
The lions were enormous in size.
It took eight men to carry the carcass back to camp.
Today, they are on permanent display along with the original skulls.
The exact number of people killed by the lions is unclear.
Pattersons figure of 135 victims is believed to be exaggerated.
The actual number is likely around 35, arrived by analyzing samples of hair and bone of the lions.
