I recently happened to watch the movie Troy and I noticed something peculiar. When the Trojans learnt of the Greek army sailing to Troy, they set about preparing for a battle. And one of the first things they did was set up huge wooden spikes along the length of the Trojan beach. The spikes were positioned towards the Aegean Sea. When the Greeks, led by Achilles, landed and captured Troy, none of the soldiers or horses were harmed by the huge spikes.
Following the successful capture of the Trojan beach, the Greeks reversed the direction of the spikes towards the Trojan mainland. Initially I suspected that the Trojans set up the spikes when the tide was low, and they would be hidden in shallow waters when the tide rises, to damage the Greek ships as they came ashore, thus destroying their ships and some of their supplies and gaining an edge in the battle. However, none of that happened. So were the spikes placed to simply add flair to the background from a cinematic perspective?
