Help with button ID please

[Ewell’s retreat]

I found this button this past Saturday and have been trying to do some research on it. There are no markings on the front but the back says “double gilt all over”. I know double gilt is common for buttons but I’m having a hard time pinpointing this one since it also says “all over”. Does anyone have any info they would enlighten me with?
