The Slim's Castle attendant directed Barrow to the Red Crown office in the tavern building. What he didn't know was that the Red Crown was a favorite gathering spot of the
Missouri Highway Patrol, in the days before two-way radio in patrol cars, when "officers and supervisors would often meet somewhere at mealtimes to exchange messages and receive orders". The Red Crown manager, Neal Houser, was immediately suspicious when Blanche entered the office in tight, provocative
jodhpurs (riding breeches), an outfit unheard of in Platte City and one much discussed at the time and still remembered by eyewitnesses forty years later. She booked both rooms out back for three guests, one night, then paid the $4 with a fistful of small change. A short time later, the young woman reappeared at the tavern's restaurant and bought five chicken dinners and five beers for the party of three. She paid for them with more small change. Houser insisted on following Blanche back to the cabins to record the car's license plate number but had to content himself with just peering into the garage for it when Clyde wouldn't let him into the cabin. revealing another flaw in his selection of the Red Crown: with only two units, there were no other guests with whom to blend in. This was apparent to everyone but the outlaws: even
The Platte County Landmark noted "Windows curtained with newspapers, continually peeping out of windows by the gang, refusing to admit any of the station [tavern] employees to the cabins, hiding from view all of the members except one woman, created a suspicion on the part of Neal Houser ..." Blanche appeared again, again in her jodhpurs, again buying five meals for her party of three, and once again paying in small change. This time, she felt the air of suspicion around her and when later she learned his identity, realized it had been the eyes of Platte County Sheriff
Holt Coffey boring into her as she completed her transaction. Blanche got a bad feeling from Houser as she handed more coins into his hands, but when she apprised Barrow of her fears, "Clyde said it was just my imagination, that everything would be all right. So I said no more." (BAR)-boosted firepower of Bonnie and Clyde. It was not just her imagination. Red Crown manager Houser had lawman restaurant patrons other than Sheriff Coffey—namely Captain William Baxter of the state patrol. Houser had a word with Baxter about his suspicions concerning his motel guests, and Baxter spoke with Coffey. When the hotelier mentioned the Oklahoma plates on their car, the officers began wondering who might be in the cabins with the taped-over windows, which limited visibility in both directions. Later that afternoon, Sheriff Coffey got a call from Louis Bernstein, the druggist at Platte City Drugs, about a stranger who had just left his store: "a good-looking gal in a slinky riding habit", the eager pharmacist reported. Both drug stores and law enforcement agencies had been alerted by Oklahoma, Texas, and Arkansas officials to be on the lookout for strangers seeking certain medical supplies. The stranger was Blanche, buying bandages and
atropine sulfate to treat Bonnie's leg burns. For Coffey and Baxter, Bernstein's call pushed the situation to high alert: if the guests had bought burn wound supplies, it may well be the scorched Bonnie Parker and the Barrows within the brick cabins. Although "[m]ost of the general public had never heard of them", Coffey's was just a county sheriff's operation—"no protective gear, no radios, no weapons to speak of other than 'squirrel rifles and a few pistols". Even with Baxter's help, both men knew they were seriously outgunned. Platte County prosecutor David Clevenger suggested they confer with Jackson County Sheriff Tom Bash in nearby Kansas City, a big-city jurisdiction "whose available armaments included machine guns, steel bulletproof shields, tear gas launchers, and armored cars". Coffey headed over to Bash's Kansas City office, but did not get the response he had hoped for. "I'm getting pretty damn tired of every hick sheriff in the country coming in here and telling me they have a bunch of desperadoes holed up and wanting help. I'm afraid there's nothing I can do for you," Bash said. Coffey was tenacious and eventually got Bash to agree to supply some men, some weaponry, bulletproof shields, and "a bulletproof car". Word was getting around town that there might be a replay of the "Kansas City Depot job" out at The Junction. Participants and spectators began gravitating to the tavern and to Slim's Castle across the road as the sweltering July day led to a muggy July night. The assault force numbered twelve: five from Platte County (Sheriff Holt Coffey, Constable Byron Fisher, Constable Thomas Hullet, Deputy James Thorpe, and Deputy Clarence Coffey), four from Jackson County (Sheriff Thomas B. "Tom" Bash, Deputy George Highfill, Deputy George Borden, and Deputy Lincoln Baker), and three from the state patrol (Capt. William Baxter, Sgt. Thomas Whitecotton, Jr., and Trooper Leonard "L. A." Ellis). Coffey and Baxter thought it best to wait until later to make their move, She told her husband about the ominous behavior of the crowd in the tavern, and he told her to go to the other cabin and tell Clyde. They apparently still were not speaking. Clyde, despite his often-cited "sixth sense" about impending danger, was unconcerned and told her not to worry about it. "Okay,' I said. 'If we all get killed here tonight, you can't say I didn't warn you." She returned to her own cabin, followed shortly by Jones with a message from Clyde: he wanted her to fetch more food. This angered Blanche and she told Jones to tell Clyde that she wasn't going out any more that night, which angered Clyde. The lawmen watching the cabins were surprised when, at about 10:30 pm, one of the doors opened and a young man emerged. Up to this point, it had been the slender woman in the riding breeches who had done all the errand-running. Seventeen-year-old W.D. Jones crossed the road, went into Slim's Castle and ordered five sandwiches and five bottles of soda pop. Clerk Kermit Crawford noticed the young man seemed nervous and kept peering over at the people milling about in the Red Crown parking lot. ==The gun battle==
