At 4:00 p.m. on the same day, the Vietnamese army sent a telegram about the exchange of wounded soldiers: To the Commander of the French Expeditionary Force in Dien Bien Phu – “stop” - We have received your notice about our wounded soldiers. We are waiting for instructions from our superiors and hope to be able to reply tomorrow to let you know the meeting time – “stop” - Signed by the Regiment Commander of the Vietnam People's Army located east of Dien Bien Phu.
During the day, the Vietnamese military medical agency reported that 240 wounded soldiers were “in bed” while 350 others were still “sitting” in the cramped tunnel. Any wounded soldiers who do not need regular medical supervision will be returned to the unit. The total number of wounded soldiers at the clinic and in the unit at that time was more than 1,500 people.
At 6:00 p.m. on April 9, 1954, the enemy used two Helldiver aircraft from the aircraft carrier Arromanches to fly low over Route 41 to search and attack Vietnamese convoys on their way to the front, in which one enemy aircraft was shot down by Vietnamese anti-aircraft artillery located in Him Lam west of Na Noong (Claudine 4). That same night, France continued to add 77 paratroopers and 195 tonnes of supplies to Dien Bien Phu, but the enemy only collected 6 tonnes of supplies.
