10/4     Contact between IR3 and IR6.  
11/4 02:00   Last contact between IR3 and HOK. The phone call is handled by a captain at guard at HOK, and he says that there are no orders for IR3. No higher officers are brought to the phone. All later attempts to get a phone connection between HOK and IR3 failed. The unfortunate outcome of this talk was probably a major reason for the surrender of IR3 two days later.
