The Strategy… Failed?! (作戦…失敗!?, Sakusen… Shippai!?) is chapter 186 of the original Naruto manga.
Having been forced the activate level two of their cursed seals during the earlier fight with the Konoha ninja, the Sound Four rest. The Sasuke Recovery Team, observing them, determines that Sasuke is likely in the coffin the Sound Four have with them. They approach, but are quickly attacked. Although the Sound Four believe they have stopped an ambush, they discover that they have been captured by Shikamaru's Shadow Imitation Technique. Sakon is somehow able to free them and Jirōbō immediately traps them in a rock prison that the Retrieval Team is unable to escape from. The Sound Four continue on while Jirōbō stays behind, which Neji discovers to be because he is absorbing their chakra.
