KARACHI, Pakistan, April, 11 — The Pakistani Government said tonight that its army had wiped out two companies of Indian troops in an engagement in East Pakistan, near Jessore yesterday.

The announcement was made by the Pakistan radio.. It was the largest reported military clash between Pakistan and India since last month's crackdown by the Pakistani Government on what it calls “miscreants” in East Pakistan. In dian‐Pakistani relations have deteriorated swiftly since then, and Pakistan has accused India of having sent infiltrators into East Pakistan to stir up trouble.

The radio said the two Indian companies from the Border Security Force, had been routed and had suffered heavy casualties in the fighting, which it said was “in the Benapol area.”

Benapol is a town in East Pakistan two or three miles from the Indian border. It lies on the route between Calcutta and Jessore, which was formerly famous as a center for the production of indigo dye.

Infiltration Mission

The radio reported that two captured Indians had said the companies had been moved near the Indian‐Pakistani border recently and then sent on an infiltration mission that took them 15 miles into Pakistani territory.

The prisoners were said to have reported that their battalion, commanded by a lieutenant colonel, had set up headquarters at Bangaon, Just west of the border opposite Benapol, on April 3.

Their reported account fitted In with Pakistani Government reports that India has been massing troops along her border with East Pakistan. Five divisions are said to have been in west Bengal earlier, and more troops were reported to have been flown in recently.

The prisoners were said to have reported that the two companies—of undisclosed size —had been sent across the border into the Jessore district, which includes Benapol.

The Pakistani authorities published today an appeal to East Pakistanis to trust the Government and return to work if they have not already done so.

The Dacca administration also denied Indian reports that heavy fighting was continuing in the east, calling them “mischievous propaganda.” In a communiqué broadcast late today it said “the patriotic armed forces and the people of East Pakistan are working shoulder-to‐shoulder to destroy antinational and antistate and armed Indian infiltrators.”

The Pakistani press and radio seemed to be trying to forge national unity by underscoring what they say is the threat posed by Indian infiltrators and a continuing build‐up of Indian forces. Declarations of support for the Government were listed from all over—from East Pakistani notables, from West Pakistani tribal chiefs and even from the Islamabad Rotary Club.
