Cazin sat at the center of the Bihać enclave (in fact, the area was often called "Cazinska Krajina"), and all lines of communication ran through it.

The start was delayed four days, however, by problems in regrouping units, mobilizing additional SVK and Krajina Serb MUP personnel to replace the missing VRS troops, and an ARBiH spoiling attack.

OG "Pauk" and TG-1, however, smashed the weak 517th Light Brigade around Šturlić, quickly driving ARBiH troops back more than 2 kilometers by 20 July.

To meet this development, 5th Corps staff quickly alerted the 502nd Brigade to rush the rest of its available troops from the Bihać city area to the site of the breakthrough.

[3] Barely checked by the arrival of the Bosnian reserves, the SVK advance continued to the east of Šturlić, and by 21 July the KSJ penetration had extended to 7 kilometers.

OG "Pauk" and TG-1's continuing drive had brought the SVK another 2 kilometers into the pocket since 23 July, and it had seized key positions at Pecka Brda, Liskovac, and Krivaja.
