The Convention protected military hospitals and ambulances while they
cared for wounded and sick combatants, and extended the same “neutrality”
to medical, administrative, and transport personnel while on duty. It
protected inhabitants who helped the wounded and required the wounded or
sick to be collected and cared for regardless of nationality. Its red
cross on white identified protected hospitals, ambulances, evacuation
parties, and authorized personnel
(1864 Convention, arts. 1–7).
The emblem reversed the colours of the Swiss flag. The founding records
did not define it as a Christian badge, but later objections to perceived
religious meaning contributed to the use and eventual legal recognition
of other emblems. The cross should therefore be explained in its Swiss
founding context without assuming that all later observers experienced it
as culturally neutral (ICRC emblem history).
The treaty did not create a general law for every person harmed by war. It
concerned wounded and sick combatants in armies in the field and the people
and facilities caring for them. It did not comprehensively protect
civilians or prisoners of war, and it did not apply to naval warfare.
Implementation rested with commanders acting on government instructions;
observance still depended on ratification, military knowledge, and conduct
in particular wars (1864 Convention, arts. 8–10).
