mr. smyser, if he'll answer, was that conversation between kennedy and clay on the 27th of october, was that something that was in these documents? thank you. >> okay. thank you. i'll start. was it known previously publicly that ulbrecht had wanted to close the border? not to the extent that it's clear in the documents. people knew there was a refugee crisis and that it was probably putting his regime at risk. so, you know, you put two and two together and, you know, people knew that he was more impatient than khrushchev was in doing something about it. so there was a general feeling ulbricht obviously is going to want to get control of this situation. but the details of the ongoing discussions about this and plans and conflicts, those details weren't known until i got those documents in moscow and berlin. i first published -- they are not part of these. those documents i initially published some in, in fact, 1993 with the cold war international history project. they are up on the website of the cold war international history project. i think -- i translated a bunch of documents into english
