Putting aside the Sisyphean task of a minute by minute account of a war involving approximately 300000 combatants, there's a major problem of the Syrian archives. Ideally, a military history examines all sides of the conflict and even before the Syrian Civil War the Assad regime guarded access to its archives. When Michael Oren wrote Six Days of War, he used Israeli intelligence reports and selected interviews to get the Syrian side of events.

Although it's against Askhistorians' rules to engage in speculation, there's a good possibility that the Syrian Civil War is probably going to make reconstructing the Syrian contribution to the Six Day War even harder. There are precedents for this; both Germany and Japan's archives suffered from both deliberate and accidental destruction over the course of losing the Second World War. One of the frustrating answers to a reference question for historians of Germany is to find a catalog record of a primary source only to get an the answer "destroyed by the war" when requesting access to it.
