 The most severe of what came to be known as "the Border Battles" erupted during October and November around Dak To, another border outpost in Kon Tum Province. The clashes there between the four regiments of the 1st North Vietnamese Division, the U.S. 4th Infantry Division, the U.S. 173rd Airborne Brigade, and ARVN infantry and Airborne elements, lasted for 22 days. By the time the fighting was over, between 1,200 and 1,600 North Vietnamese and 262 U.S. troops had lost their lives. MACV intelligence was confused by the possible motives of the North Vietnamese in prompting such large-scale actions in remote regions where U.S. artillery and aerial firepower could be applied indiscriminately, which meant that tactically and strategically, these operations made no sense. What the North Vietnamese had done was carry out the first stage of their plan: to fix the attention of the U.S. Command on the borders and draw the bulk of U.S. forces away from the heavily populated coastal lowlands and cities.
