Ca pourrait donner un truc genre:
Dear mum and Dad.
We finally arrived in Tanh Sonh Nut yesterday and achieved our first dayly patrol.
The weather is terrible, and we are soaking wet out of heat, during the whole part of the day.
The country seems only made of rice fields managed by billions little farmers with cone shaped hats.
They are brave guys for the greates part of them, but we know that some of them can be Viet cong soldiers, so we stay alert every time we meet them.
This country also seems to be the paradise of mosquitoes. They are the main vector for malaria.
This morning, a chopper picked us up in the compound, and dropped us on the landing zone.
We made our way back on our own. Fortunately, nothing happened today, but in a ´cafe´, in town, I have met guys who have been shot at by the viet cong. They told me that it happens almost everyday.
But don´t worry, I take care of myself...
Voilà, mon p´tit gars, je suis plus bien sûr de la grammaire, mais ça devrait déjà t´aider.
Bonne année.
