I guess fonseka wants to finish the major part of the battle before the rain.. means to capture nachikuda and eventually clean the pooneryn and secure the coastal lines..
My feeling is that SLA will slow down a bit now and will focus on harvesting 10 per days. That is what happening over the last few days. LTTE is furiously defending the Nachchikuda because they now that once Nachchikuda falls to SLA, then next target is Pooneryn. Once the SLA is in the visinaty of Pooneryn, LTTES logistics between india will be lost and this will directly effect Kili. So now they are putting their so called elite force to defend the nachchikuda FDL. Therefore, I think this is a good time for the SLA to harvest LTTE elite force.

WANNI: FIGHTER JETS, conducting another air sortie this morning (8) at about 8.45 a.m., hit the LTTE defence line in NACHCHIKUDA, to the west of A-9 road.
Tiger terrorists with the intention of thwarting advance of the troops have built a long protective wall for their defence parallel to the NACHCHIKUDA sea border extending towards POONERYN area. Pilots confirmed the target was accurately taken.
This shows how important Pooneryn for LTTE.
