Shanghai Volunteer Corps April 4 1854 Cap Badge

An SVC cap badges from April 4 1854 – a little special as it commemorates The Battle of Muddy Flat on that date. Units of the SVC joined British and American military units (I think the first time US and GB troops fought together after the American War of Independence) repelling Qing imperial troops besieging the rebel-held city ignored foreign demands to move further away from the foreign concessions.
