Pakanbaru

In the first light of dawn, the sleepy Siak River town of Pakanbaru was wakened by the tumultuous honking and crying of thousands of disturbed jungle birds.

As easily as that, the Indonesian government last week regained control of Pakanbaru, the heart of the U.S.-owned Caltex oilfields.

But though the rebels had done badly in their first battle with government troops, there was evidence that Pakanbaru might be a Pyrrhic victory for Sukarno.

In the eastern foothills of the Sumatra mountains, government troops from the oil center of Pakanbaru had pushed the rebels back within 70 miles of Bukittinggi.

Guns cracked in the jungles of West Java; government bombers winged over Pakanbaru in Sumatra and Menado in the Celebes, blasting radio transmitters and telephone exchanges; government patrol boats, cleared for action, blockaded rebel-held ports.
