Last Video, this secondary source was created by BazBattles, a person who illustrates ancient battles. It is a very nice visual demonstration of the battle, and the information seems to match up with other sources.
Another video on Tyre. This is a secondary srouce made by the history channel, so tread with cation as it may have "amped" up the event to make it more entertaining. I suggest to use the quotes from the primary sources, otherwise an entertaining way to learn I guess.
Video of the Battle, this secondary source was created by Scott Bartell for the University of Wisconsin-Green Bay, who is an Independent Historian/Writer. It has lovely visuals and is a good starting ground to grasp a shaky understanding in the Siege. It was shown to us in class, and so is as credible as Ms Jenkinson thinks it is. If unsure, check with the other sources to see if the information matches up.
This is a secondary article focusing more on Alexander's battle strategies. the author Marc G. DeSantis, is a historian who has written extensively on military historical subjects meaning the that information in this article and be considered reliable.

This is a primary source from Diodorus. He like Arrian, wrote events from Alexander's life., he lived in Ceasar's time, which was a wee while from Alexander's time, and he wrote from second-hand (so to speak), accounts from Alexander's soldier's viewpoint and commanders, so take with a grain of salt as these accounts were for entertainment and made to make Alexander look good. However both Diodorus and Arrian's accounts are agreed by most Historians to be possible the more accurate primary sources, so take care.
This is a primary source from Arrian. It can be considered reliable, but Arrian’s work was dated to be written four centuries after Alexander’s death, so most of his work is based on stories he heard, so that even they could have been wrong or stretched for entertainment value, especially towards Alexander’s favour. So take the information with a grain of salt. I have also included a source from Diodorus, another Primary source for comparison. This is good for quotes!
