Some detail on the Allied side, Sir.
First, regarding operations against the Konigsberg:
A Curtiss Type F flying boat (

In short order the machine suffered radiator failure and after this was repaired, a write-off crash by the end of November, 1914. A second Curtiss was acquired (type not known), and this crashed in mid-December.
Initially a pair of Sopwith 807 float-planes(

In April 1915 three Short 135 float-planes (

In June, four more aeroplanes arrived ---
Two Farman F27 'steel Farman' (

Two Caudron G.3 (

These conducted the actual shoot which wrecked the Konigsberg on 6 July, 1915.
Short 827s arrived shortly after. Some went on to Basra, and some continued to operate off ships on the coast.
Windsock no. 94, Caudron G.3, has a great deal of detail on the Koniogsberg operation.
Land-based air operations in German East Africa were conducted by No. 26 (South Africa) Squadron, arriving in Mombasa at the end of January, 1916. It was equipped with eight B.E. 2c aeroplanes
(

Land-based operations were conducted in German East Africa by 'No. 7 Squadron, R.N.A.S.' (this unit has no connection with the later European-based 7 Sqdn, RNAS which became 207 Sqdn RAF). equiped with Voisin Type L (

I have seen only mention, without any details, so far, of English aerial operations in German Southwest Africa.
The Belgians on Lake Tanganyika operated four Short 827 floatplanes (
