Loading troops and equipment back onto waterborne transport vessels

[burroughs]

Fighting in the French Indochina as CEFEO I have encountered again an apparent issue; once I commanded a Dinassaut force and I have just remembered that my problem was that at some point I had unloaded part of the force to sweep the river banks, but then it turned out that they are unable to get back to the LCIs. Same here again, the French support troops dismounted their sampans and now they cannot get back. Am I wrong or there is really no way in SB to get onto the boats back after prior disembarkation?
