The plural form of cracksman; multiple skilled burglars or safecrackers.
Standard English plural of 'cracksman,' formed by replacing the '-man' suffix with '-men', following the pattern used in English for agent nouns (fireman/firemen, policeman/policemen).
The existence of this plural suggests cracksmen were common enough in 19th-century crime that people needed a specific collective noun for them—it's like how 'hackers' only became a common plural after computers became widespread.
