The Hungarian crisis will be discussed tonight by a revolutionary leader who escaped from Hungary 13 days ago. In the fight against the Russians, he commanded a unit of 5,000 armed rebels.

The speech, at 8 p.m. tonight in the New Lecture Hall, will begin a nationwide campaign by the 22-year-old Hungarian to rouse the United Nations' and United States' support for his country.

Using the pseudonym of "Istvan Laszlo," he testified yesterday before the Senate Internal Security Committee. The chance of recognition by Soviet agents was further reduced by the white gauze surgical mask he wore.

He told the Committee that he had seen the torture chambers in which the secret police would crush their victims to death, and then cremate the remains.

Last January Laszlo was forced to leave the communist youth organization and was held by the secret police for two days.

Speaking through a translator, Laszlo testified that many Russian troops refused to fight the Hungarians, but were eventually "terrorized" into shooting by their officers and the "tougher" divisions sent from Russia as reinforcements.

Laszlo escaped from Budapest with the aid of the International Rescue Committee as Russian tanks began to roll into that city. On November 5 he flew to the United States with a member of Imre Nagy's revolutionary cabinet.

Zbigniew K. Brzezinski, assistant professor of Government will make a few analytical comments before Laszlo makes his address. The meeting is sponsored by the CRIMSON and the Student Council in cooperation with the National Student's Association.
