Aqaba 1917!
Meggido as an air-land battle (especially for the aerial destruction of the retreating Turkish forces)
By Group Captain John Alexander
The brief and ridiculous Battle for Lake Tanganyika (and go on then - the wider Tabora offensive, if boats make you feel sick). Not an area of the war I can remember anybody talking about ever.
Butte de Vauquois as a prime example for mines and the underground war. Had a mobile and a static phase, includes some ridicolous oversized unrealized German plans, demonstrates the widespread destructions - it is an all-in-one.
Irles in 1917 with the 18th division is a really interesting engagement with loads of moving parts, with changes in dynamics of strategy, weather and combined arms as well. Talked about in 'With the 10th Essex in France'. Second Piave as well, lots of forces within and moving parts.
There are various examples in Africa if you want to consider a different theatre - Tanga 1914, Mahiwa 1917, GSWA 1914/5 - not quite a battle but interesting that out of 6 months official conflict there were only 26 days of action (rest moving equipment etc)... Kōnigsberg for naval and, and, and...
I don't remember the exact battle (perhaps Messine?) but when I was studying it I was fascinated at the concept of defeating trench warfare with the "bite and hold" tactic. All defenses were planned assuming the assault would try to breakthrough and encircle...
Messines, the Brusilov Offensive, and the Salonika Offensive (1918) for starters.
I really just want to pitch "the air war!" but I'm trying to come up with specifics... maybe the use of air power at the Somme in 1916, or the RFC in the Middle East?
