This was the first break in the ranks of the band, the first instance in which they had suffered for their crimes. But the bold spirit of the organization was still unbroken. Three brothers still remained to replace the one who was gone; and so far from learning caution, the band launched forthwith into still more daring and frequent offenses. Trains were "held up" right and left; robberies were committed; and early in 1868 the gang made a famous raid across the country through Indiana and Illinois, robbing safes in county treasurers' offices in a number of places. In several instances some of the members were arrested; but they always managed to have the prosecution quashed, or in some way to escape conviction. In the spring of 1868 their operations became so outrageous, and the situation so serious, that Allan Pinkerton was again called upon to do something in the cause of public safety.

In March of this year the safe of the county treasurer at Magnolia, Harrison County, Iowa, was robbed of about fourteen thousand dollars; and Allan Pinkerton detailed his son, William A. Pinkerton, and two assistants, to run down the burglars. Arrived at the scene of the robbery, the detectives found that the thieves had made their escape on a hand-car and had gone in the direction of Council Bluffs. At this time in Council Bluffs there was a low saloon, kept by a man who had formerly lived in Seymour and who was known as a bad character. It was decided to keep a sharp watch on this resort, Mr. Pinkerton reasoning that since Seymour was the friendly refuge of the Renos, it was altogether likely that the outlaws would have a friend, and perhaps an abettor, in the saloon-keeper who had once lived there. After two days' watching, the detectives observed a large man of dark complexion enter the saloon and engage in close conversation with the proprietor, having with him, evidently, some mysterious business.

Investigation disclosed this man to be Michael Rogers, a prominent and wealthy citizen of Council Bluffs, and the owner of an extensive property in the adjoining counties. Puzzled, but still persuaded that he had found a clue, Mr. Pinkerton put a "shadow" on Rogers, and hurried back to Magnolia, where he learned that on the day preceding the robbery Rogers had been seen in Magnolia, where he had paid his taxes, and in doing so had loitered for some time in the treasurer's office. This also looked suspicious. But, on the other hand, search as he might, the detective could find nothing against Rogers's character, every one testifying to his entire respectability.

Still unconvinced, Mr. Pinkerton returned to Council Bluffs, where he was informed by the man who had been "shadowing" Rogers that several strange men had been seen to enter Rogers's house and had not been seen to come out again. The watch was continued more closely than ever, and after four days of patient waiting, Rogers, accompanied by three strangers, was seen to leave the house cautiously and take a west-bound train on the Pacific Railroad. One of these men, a brawny, athletic fellow nearly six feet tall, and about twenty-eight years of age, Mr. Pinkerton shrewdly suspected was Frank Reno, although he could not be certain, never having seen Frank Reno. Feeling sure that if his suspicions were correct the men would ultimately return to Rogers's house, Mr. Pinkerton did not follow them on the train, but contented himself with keeping the strictest watch for their return. The very next morning the same four men were discovered coming back to the house from the direction of the railroad. But at that hour no train was due, which was a little curious; and another curious point was that they were all covered with mud and bore marks of having been engaged in some severe, rough labor. The hour was early; the dwellers in Council Bluffs were not yet astir. A little later the city was thrown into a fever of excitement by the news that the safe of the county treasurer at Glenwood, in Mills County, about thirty miles distant, had been robbed the previous night. No trace had yet been got of the thieves, but everything indicated that they were the same men who had robbed the safe at Magnolia. One remarkable point of similarity in the two cases was the means employed by the robbers in escaping, a hand-car having been used also by the Glenwood thieves; and they, too, were believed to have fled in the direction of Council Bluffs. Investigation soon made this absolutely certain, for the missing hand-car was found lying beside the railroad, a short distance from the Council Bluffs station.

Putting these new disclosures beside his previous suspicions and discoveries, Mr. Pinkerton was further strengthened in his distrust of the man Rogers; and although the local authorities, to whom he revealed his suspicions, laughed at him, declaring that Rogers was one of the most respectable citizens of the State, he resolved to attempt an arrest. Proceeding to Rogers's house with all the force he could command, he placed a guard at front and rear, and then, with a few attendants, made his way inside. The first person he met was Mr. Rogers himself, who affected to be very indignant at the intrusion.

"Who have you in this house?" asked Mr. Pinkerton.

"Nobody but my family," answered Mr. Rogers.

"We'll see about that," answered Mr. Pinkerton; and then, turning to his men, he ordered them to search the premises.

They did so, and soon came upon the three strangers, who were taken so completely by surprise that they made no effort at resistance. They were about to sit down to breakfast, which was spread for them in the kitchen. A comparison with photographs and descriptions left no doubt that one of the three was Frank Reno. A second—a man of dark complexion, tall, and well built—proved to be Albert Perkins, a well-known member of the Reno gang. The third was none other than the notorious Miles Ogle, the youngest member of the band, who afterward came to be known as the most expert counterfeiter in the United States. Ogle at this writing is in the Ohio penitentiary, serving his third term of imprisonment. At his last capture there were found in his possession some of the best counterfeit plates ever made.

While they were securing the four men the detectives noticed that smoke was curling out of the kitchen stove, accompanied by a sudden blaze. Mr. Pinkerton pulled off a lid, and found on the coals several packages of bank-notes, already on fire. Fortunately the notes had been so tightly wrapped together that only a few of them were destroyed before the packages were got out. Those that remained were afterward identified as of the money that had been stolen from the Glenwood safe. There was thus no question that these were the robbers so long sought for. A further search of the house brought to light two sets of burglars' tools, which served as cumulative evidence.
