These show a series of rocket attacks on Vung-Tau. Hi Vic, Here are two maps I compiled from the Army commanders diary entries (the link to which is below) the diary is 9.7mb in size in adobe format and the relevant pages are 30, 121 and 122 (adobe numbers) depending on your internet connection you may not want to download the whole file in which case I can email just those pages. The whole thing however may make interesting reading and that link will lead you to other diaries for other years.  I went up to 366 and they have not received any mail to my name yet.
