three other Scouts, whom Nellist tasked to deliver the report to Mucci. Nellist and Vaquilar remained in the shack until the start of the raid. Mucci had already been given Nellist's January 29 afternoon report and forwarded it to Prince, whom he entrusted to determine how to get the Rangers in and out of the compound quickly, and with as few casualties as possible. Prince developed a plan, which was then modified in light of the new report from the abandoned shack reconnaissance received at 14:30. He proposed that the Rangers would be split into two groups: about 90 Rangers of C Company, led by Prince, would attack the main camp and escort the prisoners out, while 30 Rangers of a platoon from F Company, commanded by Lt. John Murphy, would signal the start of the attack by firing into various Japanese positions at the rear of the camp at 19:30. Prince predicted that the raid would be accomplished in 30 minutes or less. Once Prince had ensured that all of the POWs were safely out of the camp, he would fire a red flare, indicating that all troops should fall back to a meetup at Pampanga River north of the camp where 150 guerrillas would be ready with carabao-pulled carts to transport the POWs. This group would help to load the POWs and escort them back to American lines. One of Prince's primary concerns was the flatness of the countryside. The Japanese had kept the terrain clear of vegetation to ensure that approaching guerrilla attacks could be seen as well as to spot prisoner escapes. Prince knew his Rangers would have to crawl through a long, open field on their bellies, right under the eyes of the Japanese guards. There would only be just over an hour of full darkness, as the sun set below the horizon and the moon rose. This would still present the possibility of the Japanese guards noticing their movement, especially with a nearly full moon. If the Rangers were discovered, the only planned response was for everyone to immediately stand up and rush the camp. The Rangers were unaware that the Japanese did not have any searchlights that could be used to illuminate the perimeter. Pajota suggested that to distract the guards, a United States Army Air Forces (USAAF) airplane should buzz the camp to divert the guards' eyes to the sky. Mucci agreed
