If you click to let the video fill the screen you'll see the dates just
above the map at the left. They are hard to read, as are the captions at
the lower left that describe the major events taking place. An earlier
version had larger dates at the center on the bottom, along with an
(annoying) sound track.
SHUCHAT (Talnoye, Simferopol, Sevastopol, Odessa, Balta (Abazovka),
VINOKUR (Talnoye), KURIS (Mogilev-Podolskiy, Ataki, Berdichev)
SILVERMAN (Soroki, Kremenets), BIRNBAUM (Kamenets-Podolskiy)
I would find this video infinitely more useful if there were any way
that I could see to correlate any given map with a time-frame.
