Harry could be a great asset in terms of leadership. In the wizarding world, he has led his friends through many difficult situations. At Helm's Deep, he could inspire the soldiers with his courage and determination. He might even use his Parseltongue ability to communicate with any snakes in the area (if there are any) and use them to his advantage, like getting them to distract the orcs while the defenders make a strategic move.
Harry might use his Patronus charm. If the orcs are affected by fear, his stag Patronus could charge through their ranks, causing chaos and fear among them. Also, his knowledge of potions could be useful. He could brew some sort of potion that gives the defenders extra strength or stamina for the long battle at Helm's Deep.
He could use his flying skills on a broomstick to scout the enemy. Just imagine Harry on his Firebolt, flying high above Helm's Deep, seeing the approaching army of orcs and relaying the information back to the defenders.
The Battle of Helm's Deep of the Lord of the Rings was a fictional war in the fantasy novel The Lord of the Rings by the British writer Tolkien. The two parties involved were Saruman's army and the Rohirrim who had taken refuge in Helm's Deep, led by King Theoden. Theoden led his army to reinforce Okenbrand, who was engaged in a fierce battle with Saruman's army. However, Okenbrand's troops had already been scattered before they arrived. Gandalf suggested that Theoden should be stationed at the Hornhorn Fort at Helm's Deep, where many people of the Western Region had fled the war. Helm's Deep was commanded by Gamlin, and the women and children were gathered in Dunharrow by Aeowyn. The elves 'participation in the Battle of Helm's Deep was an adaptation of the movie version. There were no elves participating in the battle in the original novel.
One possible plot could be that Harry and his friends accidentally get transported to the Battle of Helm's Deep. They use their magic to turn the tide of the battle in unexpected ways. For example, Hermione could use a spell to make the walls of Helm's Deep even stronger, while Harry and Ron lead a group of wizards to fight off the orcs from above using broomsticks.
Obviously, Harry Potter himself would be a main character. He could bring his skills and courage from the wizarding world to the Battle of Helm's Deep. Hermione Granger would also be there. Her vast knowledge of magic could be crucial in finding solutions during the battle. Ron Weasley too, with his loyalty and his own brand of wizarding skills. Maybe Hagrid could also be involved, his huge size and strength being an asset in the physical combat at Helm's Deep.
The characters who appeared in the Battle of Helm's Deep were Legolas, Pippin, Meryl, Gandalf, Aragorn, Kinley the Elf, Theoden the King of Rohan, Sauron, Saruman, Aragon, Aeomer, and Haldier.
In the Battle of Helm's Deep in the Lord of the Rings movie series, the existence of the elven general was not explicitly mentioned in the search results provided. Therefore, based on the information provided, it was impossible to determine whether an elven general had participated in the Battle of Helm's Deep.
The Battle of Helm's Deep in The Lord of the Rings 2: The Two Towers had a key difference from the original novel. In the original novel, there were no elves involved in the battle at Helm's Deep, but in the movie, it was decided to let elves participate in the battle to show the unity of the free people of Middle-earth and the sacrifice of the characters. Therefore, it could be said that the movie was an adaptation of the Battle of Helm's Deep.
The Battle of Helm's Deep in The Lord of the Rings 2: The Twin Towers was a famous battle that took place on the night of March 3rd to the dawn of March 4th, 3019 in the Third Age. In this battle, the Rohirrim, under the leadership of King Theoden, successfully repelled an army of 10,000 Orcs, Uruk-Orcs, and Dunlanders led by Saruman. The Battle of Helm's Deep ended with the victory of the humans, which led to the larger defense of Minas Tirith. This battle was presented brilliantly in the movie. It was a magnificent scene.
One possible plot could be that Harry uses his magic in ways that are unexpected in the Middle - earth setting of Helm's Deep. Maybe he uses spells like 'Protego Maxima' to create a shield around the fortress, protecting it from the incoming orcs. He could also use the 'Accio' charm to bring weapons to the defenders when they are in need.
The Battle of Helm's Deep was a famous battle in The Lord of the Rings, also known as the Battle of the Hornfort. The battle took place at Helm's Deep in Rohan. The Rohirrim, under the leadership of King Theoden of Rohan, successfully defeated Saruman's army. This battle took place on the night of March 3rd, 3019 of the 3rd era, and lasted until dawn on the 4th. The Rohirrim had successfully defended Helm's Deep against an army of 10,000 orcs, Uruk-orcs, and Dunlanders with three bugle calls. However, there was no information about the simulation game of the Battle of the Helm's Deep of the Lord of the Rings in the search results provided so far. It was impossible to know if such a simulation game existed.
It would be a very difficult fit. Since the wizarding world has its own norms like monogamous relationships in most cases (like the marriages we see in the series). If one were to introduce concubines, it would have to be in an alternate universe where the social and moral values are completely different. Maybe in a fanfic where the wizarding world is modeled after a more ancient and permissive society, but this would be a huge departure from the original feel of the Potterverse.
