Barkers plan was to hit the British defense line at the center, where most of the British troops were concentrated, this would leave the weaker lines no choice but to surrender.
After meeting with Blake and other important figures, the idea was accepted.

Taking advantage of this the punched through the British defense and advanced another 17km. This left them just 25km from Perth and advancing. Most British soldiers outside Perth had either been arrested or they deserted.
