Ninety Years Ago in Greece, Greek Independence Day, 25 March

I've posted this faded old postcard photograph before,

 but here's a clearer copy with a little more contrast:

The Greek Army in Kiretsiler 

(now Chryssa, near Xanthi) 

on 25 March, 1923

Well, it was a national holiday,
 Greek Independence Day 
(historical and religious holiday).
