When [we] ran in, [we] saw the squadron waiting. This means they ran in wherever they were running in and saw a group of military soldiers that were lined up in a military formation, called a squadron. They saw their friends waiting for them, troubled, looking out at the sea. They beached, or laid the ship (her) ashore and grounded her/the ship to shallow water in the sand. Then they got of the ship and waded through the water onto the sandy beach.
