Animated mapping uses "animation, either computer or video, to add a temporal component to a map so that change in some dimension is displayed" (Wikipedia). Animated maps depict or make visual military actions over time. Events taking place over days, months, or years can be shown at a faster pace. Some Websites providing animated maps of military battles and wars include:
CSI Battle Maps (Combat Studies Institute Battle Maps). United States Army Combined Arms Center.
http://usacac.army.mil/organizations/cace/csi/battlemaps
History Animated
http://historyanimated.com/newhistoryanimated/
Search the Web for animated maps using the search pattern
[name of the battle, campaign, or war] animated map
For example, "Sanananda and animated map" identifies (among other animated maps):
The Japanese Besieged - the Battle of the Beachheads: Buna, Gona, Sanananda
http://kokoda.commemoration.gov.au/japanese-besieged-buna-gona-sanananda/
Note: As is the case with printed publications, animated maps of specific battles may be contained within an animation of a campaign, operation, or war.
Library of Congress. Military Battles and Campaigns
https://www.loc.gov/collection/military-battles-and-campaigns/about-this-collection/
Maps of military battles and wars may be contained within books, government documents, and other publications. Maps are also contained within atlases, compendiums of maps.
To find maps, use Books/Media and enter the name of the battle or operation. With the results list on your screen, look at the left-hand column for Source Type and choose More options, then Maps.
To search for additional maps and for atlases, use the Advanced Search mode of Books/Media and construct a keyword search as follows:
first search box [battle] AND map*
OR
second search box [battle] AND atlas*
substituting the name of the battle, campaign, or operation you are researching for [battle].
For example,
"world war" AND 1939-1945 AND map*
OR
"world war" AND 1939-1945 AND atlas* to identify:
War Maps: World War II, from September 1939, to August 1945, Air, Sea and Land, Battle by Battle
