Never done it so I didn't know, thanks. Either way the ships going through at the same time doesn't necessarily mean they were together, maybe they are just 'friends with benefits'.
Gotcha. The canal groups ships coming through into convoys, which aren't that big anyway, 11 sounds about right for typical size. Considering they normally take extra measures (liaison officers) to coordinate with warships transiting through, it makes sense that to do it all at once for convenience.
And the bit about "thousands of soldiers" seems played up as well. There are already thousands of Egyptian Army troops specifically stationed to protect the Canal, and in some spots, if you're paying attention, you can see groups of tanks, and other armored vehicles in various spots.
