These were not:put into action until the closing days of the battle. The
rocket's were not mounted on trucks: but were fired from a platform which
probably has wheelS and can be errected from a truck. The caliber of the
rockets is unknown.

37mm flack in the vicinity of Hai Duong (N 20-56; E 106-19).1

Comment. The bridges across the river at Hai Duong are the most
vulnerable link in the Hanoi-Haiphong supply line. If the Viet Minh
plans to attack the area, it might well move in AL in anticipation of
French air retaliation.
