Sheet SP-1173, a 1966 Chieu Hoi program sheet in the JUSPAO printing series, reports that South Vietnamese and U.S. naval and air forces found and destroyed a Viet Cong steel-hulled supply ship on 10 May 1966. Photographs show the broken hull, a captured heavy machine gun marked as made in Czechoslovakia, mortar rounds and crates of TNT.
An exhibit on paper
The sheet is laid out like a display of seized evidence. The archive describes the photographs: the wrecked steel hull lying beside a Republic of Vietnam Navy junk, naval officers looking over a captured heavy machine gun, and rows of mortar rounds and crates of TNT. Labels are lettered into the pictures, and a headline and closing line in capitals frame the whole.

SP-1173
In the archive's English summary and its machine translation, which it labels as not verified by a fluent reader, the text reports that Vietnamese and U.S. naval and air forces found and destroyed the ship on 10 May 1966, and the closing line credits timely action by the South Vietnamese armed forces and their allies with breaking every Viet Cong plot of terror and sabotage. The machine gun is marked as made by "Tiep Khac," which the archive identifies as Czechoslovakia. The body text also gives tonnage figures ("độ 60 tấn," "độ 50 tấn"), which the archive's summary treats as part of the proof offered.
The record
FRAME's maker line calls it a "Chieu Hoi programme sheet issued under the Joint U.S. Public Affairs Office (JUSPAO) printing series for the South Vietnamese government," dated 1966. The audience is coded as the domestic public, and the purpose as persuading or winning support. The source category is "Source blurred: contractors, cutouts, buried disclosure."
Reading it
FRAME tags card stacking and fear appeal. Seized weapons are good evidence of a kind: a machine gun with a factory mark and a broken hull are hard to invent. What the sheet does with them is the propaganda. One ship becomes proof that "every" plot has been broken. The printed headline, in the archive's unverified machine translation, says the weapons "can no longer kill compatriots," and the catalog title names the intended targets as "Free Vietnamese." That is where the fear comes in.
The sheet is careful about one thing: it shows the reader where one of the guns came from, by its factory mark. It is less careful about whose sheet it is. A South Vietnamese reader saw Vietnamese and American forces credited and no sign that an American office had printed the page.
In 1965 the U.S. Information Agency's Manila sheet Aggression from the North made the infiltration case to a foreign audience, with photographs of a sunken cargo ship among its evidence. Xâm nhập draws the same argument as a map. The Vietnam War messaging hub covers the series.
