the drake (male) is only spectator. Drakes don't help raising the ducklings, they leave after the fun part. (pretty smart huh?) Maybe is watching to see if the crow is winning, that would be the best outcome for him cause then the hen will want to mate again to start a new nest

After reports of heavy siege equipment and chariots being positioned for an attack on Eastgate, the city council has commissioned new defences.
Weary from the long siege and the conflict between the now reunited brothers Dugal and Petera, the citizens, craftsmen, and soldiers have flocked to help keep the new enemy at bay.
Here, soldiers are chugging away at the hard sandstone to create a ditch deep enough to stop or topple over any siege tower or similar equipment making it's way towards the tall walls of Eastgate.

New Tavern Fort, Gravesend, Kent
New Tavern Fort is an unusually complete example of 18th century fortifications which underwent development in the 19th and 20th centuries. The fort displays a complete sequence of mounted guns representing each stage in its development, and contains a number of unusual features which have been preserved in situ. The site is known for its connection with General Charles Gordon who lived here from 1865-71 and was later killed at Khartoum. The foundations of his house still survive within the fort. The fort itself, along with Tilbury on the opposite bank of the Thames, illustrates well the strategic importance of the Thames Estuary and the methods employed to defend it over a period of 170 years. The fort is particularly well preserved, having been maintained over a number of years by the New Tavern Fort Project. In the north west corner of the fort is Milton Chantry, a 14th century building representing the chapel of a medieval hospital.
...New Tavern Fort was built as a result of the 1778 survey of the defensive requirements of the Thames. Fear of a French invasion led to the fort being built to provide cross fire with Tilbury on the other side of the river. Originally New Tavern Fort consisted of a battery on two faces forming an angle towards the river with a strip of rampart joining it to a smaller, straight battery, defended to the front by a flat-bottomed ditch containing a wooden palisade c.3m high. The fort was constructed of unrevetted earth and was designed for an armament of heavy, smooth-bore cannon firing through embrasures. The rear of the fort was originally open and unprotected but before the end of the century a brick wall, with loopholes for musketry, was added. Although the initial construction was between 1780 and c.1783, the armament of the fort was updated and increased at intervals throughout the 19th century. In the 1840s the fort was modernised to take a heavier armament, which involved the reconstruction of the older gun emplacements, but this did not alter the basic plan of the fort. A magazine designed to hold 250 barrels of powder was built close to the chantry building, and another smaller magazine, for 50 barrels, was established nearby. Other new buildings constructed at this time included a wash-house, coal store and a guardroom. Once again, in the 1860s and 1870s, the development of large guns forced improvements in the design and armament of coastal defences and so between 1868 and 1872 new brick emplacements for 10 heavy guns were constructed, with magazines below. Again, however, the plan of the fort was not altered. By the end of the 19th century muzzle-loaded guns had become obsolete, and the perceived danger from breech-loading weapons mounted on enemy warships meant that emphasis was placed on strengthening defences downstream from Gravesend, and thus New Tavern Fort lost some of its strategic importance. In 1905 concrete emplacements for two six-inch breech-loading guns were built, joined together by a walkway with a separate magazine underneath. Although the fort was garrisoned during World War I, its strategic importance continued to decline. In 1930 it was purchased by the Gravesend Corporation who laid it out as a pleasure garden for the public. During the Second World War the magazine built for the breech-loading guns was used for a time as an air raid shelter.

Israeli Paratroopers during a demonstration of weapons and equipment for visiting Israeli School Children – 15th December 2011
from Amedee Guillemin's book "Electricity and Magnetism", MacMillans 1891
the description of this arrangement proceeds thus :-
General Chazal combined the employment of electricity with that of a "camera obscura" in a very ingenious way for the defence of the Escaut by torpedoes.
Under a tent protected by fortifications he arranged the battery, or induction apparatus, from which the spark is produced. All the wires which electrically united the lines of the torpedoes with the apparatus ended separately in the tent, and each of them was numbered so as to render all error impossible. On the table was a plan of the harbour, where the positions of the lines of the torpedoes were indicated, and which was nothing else but the reproduction of the optical projection of the river by the apparatus of the camera obscura placed at the top of the tent.
Let us suppose that an enemy's ship is seen coming up the river; the officer watching and commanding could follow minute by minute the position which it occupies, relative to the lines of immersion of the torpedoes.
At an opportune moment he would give the order to the sailor in charge of the electrical apparatus, and tell him the number of the wire in which he must close the circuit.

I'm presuming this beach doesn't normally get much of a pounding, yet maybe it has recently? But it all looks in very good condition. The defences being concave in shape, repelling the force.
