Compatibilism asserts that free will remains a meaningful concept within a world of perfectly reliable cause and effect. There is no conflict between the notion that my choice was causally necessary from any prior point in time (determinism) and the notion that it was me that actually did the choosing (free will).
The only way that determinism and free will become contradictory is by bad definitions. For example, if we define "determinism" as "the absence of free will", or, if we define "free will" as "the absence of determinism", then obviously they would be incompatible. So, let's not do that.
Determinism asserts that every event is the reliable result of prior events. It derives this from the notion of a world of perfectly reliable cause and effect. Our choices, for example, are reliably caused by our choosing operation. The choosing operation is a deterministic event that inputs two or more options, applies some criteria of comparative evaluation, and, based on that evaluation, outputs a single choice. The choice is usually in the form of an "I will X", where X is the thing that we have decided we will do. Our chosen intent then motivates and directs our subsequent actions.
Free will is literally a freely chosen "I will". The only issue here is what that choice is expected to be "free" of. Operationally, free will is when we decide for ourselves what we will do while "free of coercion and undue influence". The notion of "undue influence" includes things like a mental illness that distorts our view of reality with hallucinations or delusions, or impairs the ability of the brain to reason, or imposes an irresistible impulse. Undue influence would also include things like hypnosis, or the influence of those exercising some control over us, such as a parent/child, doctor/patient, commander/soldier. It can also include other forms of manipulation that are too subtle or too strong to resist. These are all influences that can be reasonably said to remove our control of our choices.
The operational definition of free will is used when assessing someone's moral or legal responsibility for their actions.
Note that free will is not "free from causal necessity". It is simply free from coercion and undue influence.
So, there is no contradiction between a choice being causally necessitated by past events, and the most meaningful and relevant of these past events being the person making the choice.
Therefore, determinism and free will are compatible notions.
