British joint amphibious experience before Gallipoli

Did Britain lack the ability to coordinate naval and army amphibious operations before the Second World War?

No. Britain had extensive amphibious experience, and Gallipoli's coordination failure lay mainly in higher staffs and ministries.

A comment suggests that effective Navy-Army amphibious scheduling did not mature until the Second World War. The response points instead to Britain's long history of joint amphibious operations. The Royal Navy and British Army had repeatedly demonstrated that they could cooperate effectively when brought together for a defined mission. At Gallipoli, much of the dysfunction lay in the home staffs and ministries rather than among the people who would carry out the landings. The campaign therefore shows established knowledge defeated by poor direction and preparation.
