Added various maps to make escape journey clearer:-

Had to find Malay names:-
Peak Island is now Kusa Island
Sungai means river in Malay and is written before the river name (Sungai Batanghari)
Paula means Island in Malay and is written before the island name (Paula Durian)
Djambi River is now called Batang Hari River (Sungai Batanghari)
I believe this makes the journey clearer.
